A information disclosure vulnerability in the Upstream kernel encrypted-keys. Product: Android. Versions: Android kernel. Android ID: A-70526974.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):A flaw was found in Linux     kernel in the ext4 filesystem code. A use-after-free is     possible in ext4_ext_remove_space() function when     mounting and operating a crafted ext4     image.(CVE-2018-10876)A flaw was found in the Linux     kernel. A use-after-free was found in the way the     console subsystem was using ioctls KDGKBSENT and     KDSKBSENT. A local user could use this flaw to get read     memory access out of bounds. The highest threat from     this vulnerability is to data     confidentiality.(CVE-2020-25656)A flaw was found in the     way RTAS handled memory accesses in userspace to kernel     communication. On a locked down (usually due to Secure     Boot) guest system running on top of PowerVM or KVM     hypervisors (pseries platform) a root like local user     could use this flaw to further increase their     privileges to that of a running     kernel.(CVE-2020-27777)A information disclosure     vulnerability in the Upstream kernel encrypted-keys.
    Product: Android. Versions: Android kernel. Android ID:
    A-70526974.(CVE-2017-13305)A race condition was found     in the Linux kernels implementation of the floppy disk     drive controller driver software. The impact of this     issue is lessened by the fact that the default     permissions on the floppy device (/dev/fd0) are     restricted to root. If the permissions on the device     have changed the impact changes greatly. In the default     configuration root (or equivalent) permissions are     required to attack this flaw.(CVE-2021-20261)An issue     was discovered in dlpar_parse_cc_property in     arch/powerpc/platforms/pseries/dlpar.c in the Linux     kernel through 5.1.6. There is an unchecked kstrdup of     prop->name, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash).(CVE-2019-12614)An issue was discovered in     fs/xfs/xfs_icache.c in the Linux kernel through 4.17.3.
    There is a NULL pointer dereference and panic in     lookup_slow() on a NULL inode->i_ops pointer when doing     pathwalks on a corrupted xfs image. This occurs because     of a lack of proper validation that cached inodes are     free during allocation.(CVE-2018-13093)An issue was     discovered in rds_tcp_kill_sock in net/rds/tcp.c in the     Linux kernel before 5.0.8. There is a race condition     leading to a use-after-free, related to net namespace     cleanup.(CVE-2019-11815)An issue was discovered in the     Linux kernel through 5.11.3. A kernel pointer leak can     be used to determine the address of the iscsi_transport     structure. When an iSCSI transport is registered with     the iSCSI subsystem, the transport's handle is     available to unprivileged users via the sysfs file     system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)An issue was     discovered in the Linux kernel through 5.11.3. Certain     iSCSI data structures do not have appropriate length     constraints or checks, and can exceed the PAGE_SIZE     value. An unprivileged user can send a Netlink message     that is associated with iSCSI, and has a length up to     the maximum length of a Netlink     message.(CVE-2021-27365)An issue was discovered in the     Linux kernel through 5.11.3.
    drivers/scsi/scsi_transport_iscsi.c is adversely     affected by the ability of an unprivileged user to     craft Netlink messages.(CVE-2021-27364)An issue was     discovered in yurex_read in drivers/usb/misc/yurex.c in     the Linux kernel before 4.17.7. Local attackers could     use user access read/writes with incorrect bounds     checking in the yurex USB driver to crash the kernel or     potentially escalate     privileges.(CVE-2018-16276)drivers/infiniband/core/ucma     .c in the Linux kernel through 4.17.11 allows     ucma_leave_multicast to access a certain data structure     after a cleanup step in ucma_process_join, which allows     attackers to cause a denial of service     (use-after-free).(CVE-2018-14734)In create_pinctrl of     core.c, there is a possible out of bounds read due to a     use after free. This could lead to local information     disclosure with no additional execution privileges     needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-140550171(CVE-2020-0427)In     do_epoll_ctl and ep_loop_check_proc of eventpoll.c,     there is a possible use after free due to a logic     error. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for exploitation.Product:

This could lead to the size-remaining variable     wrapping and the data pointer going over the end of the     buffer. This could possibly lead to memory corruption     and possible privilege escalation.(CVE-2017-7482)In     uvc_scan_chain_forward of uvc_driver.c, there is a     possible linked list corruption due to an unusual root     cause. This could lead to local escalation of privilege     in the kernel with no additional execution privileges     needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-111893654References: Upstream     kernel(CVE-2020-0404)In various methods of     hid-multitouch.c, there is a possible out of bounds     write due to a missing bounds check.

    Upstream kernel(CVE-2020-0465)It was found that the raw     midi kernel driver does not protect against concurrent     access which leads to a double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation.(CVE-2018-10902)Linux kernel ext4     filesystem is vulnerable to an out-of-bound access in     the ext4_ext_drop_refs() function when operating on a     crafted ext4 filesystem image.(CVE-2018-10877)Linux     kernel is vulnerable to a stack-out-of-bounds write in     the ext4 filesystem code when mounting and writing to a     crafted ext4 image in ext4_update_inline_data(). An     attacker could use this to cause a system crash and a     denial of service.(CVE-2018-10880)Linux Kernel contains     an out-of-bounds read flaw in the asn1_ber_decoder()     function in lib/asn1_decoder.c that is triggered when     decoding ASN.1 data. This may allow a remote attacker     to disclose potentially sensitive memory     contents.(CVE-2018-9383)use-after-free read in     sunkbd_reinit in     drivers/input/keyboard/sunkbd.c(CVE-2020-25669)mwifiex_     cmd_802_11_ad_hoc_start in drivers/     net/wireless/marvell/mwifiex/join.c in the Linux kernel     through 5.10.4 might allow remote attackers to execute     arbitrary code via a long SSID value, aka     CID-5c455c5ab332.(CVE-2020-36158)fs/ nfsd/ nfs3xdr.c in     the Linux kernel through 5.10.8, when there is an NFS     export of a subdirectory of a filesystem, allows remote     attackers to traverse to other parts of the filesystem     via READDIRPLUS. NOTE: some parties argue that such a     subdirectory export is not intended to prevent this     attack see also the exports(5) no_subtree_check default     behavior.(CVE-2021-3178)In the Linux kernel before     4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c     mishandles reference counting because of a race     condition, leading to a     use-after-free.(CVE-2019-6974)The KVM implementation in     the Linux kernel through 4.20.5 has a     Use-after-Free.(CVE-2019-7221)A flaw was found in the     JFS filesystem code. This flaw allows a local attacker     with the ability to set extended attributes to panic     the system, causing memory corruption or escalating     privileges. The highest threat from this vulnerability     is to confidentiality, integrity, as well as system     availability.(CVE-2020-27815)An out-of-bounds (OOB)     memory access flaw was found in x25_bind in     net/x25/af_x25.c in the Linux kernel. A bounds check     failure allows a local attacker with a user account on     the system to gain access to out-of-bounds memory,     leading to a system crash or a leak of internal kernel     information. The highest threat from this vulnerability     is to confidentiality, integrity, as well as system     availability.(CVE-2020-35519)In     drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux     kernel through 5.11.8, the RPA PCI Hotplug driver has a     user-tolerable buffer overflow when writing a new     device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame     directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination,     aka CID-cc7a0bb058b8.(CVE-2021-28972)A NULL pointer     dereference was found in the net/rds/rdma.c
    __rds_rdma_map() function in the Linux kernel before     4.14.7 allowing local attackers to cause a system panic     and a denial-of-service, related to RDS_GET_MR and     RDS_GET_MR_FOR_DEST.(CVE-2018-7492)The Siemens R3964     line discipline driver in drivers/tty/ n_r3964.c in the     Linux kernel before 5.0.8 has multiple race     conditions.(CVE-2019-11486)The kernel in Android before     2016-08-05 on Nexus 7 (2013) devices allows attackers     to gain privileges via a crafted application, aka     internal bug 28522518.(CVE-2016-3857)The KVM     implementation in the Linux kernel through 4.14.7     allows attackers to obtain potentially sensitive     information from kernel memory, aka a write_mmio     stack-based out-of-bounds read, related to     arch/x86/kvm/x86.c and     include/trace/events/kvm.h.(CVE-2017-17741)The     sctp_process_param function in net/sctp/sm_make_chunk.c     in the SCTP implementation in the Linux kernel before     3.17.4, when ASCONF is used, allows remote attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a malformed INIT     chunk.(CVE-2014-7841)The XFS subsystem in the Linux     kernel through 4.8.2 allows local users to cause a     denial of service (fdatasync failure and system hang)     by using the vfs syscall group in the trinity program,     related to a 'page lock order bug in the XFS seek     hole/data implementation.'(CVE-2016-8660)The     xfs_dinode_verify function in     fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel     through 4.16.3 allows local users to cause a denial of     service (xfs_ilock_attr_map_shared invalid pointer     dereference) via a crafted xfs image.(CVE-2018-10322)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:

  - Integer overflow in the aio_setup_single_vector function     in fs/aio.c in the Linux kernel 4.0 allows local users     to cause a denial of service or possibly have     unspecified other impact via a large AIO iovec. NOTE:
    this vulnerability exists because of a CVE-2012-6701     regression. (CVE-2015-8830)

  - A weakness was found in the Linux ASLR implementation.
    Any user able to running 32-bit applications in a x86     machine can disable ASLR by setting the RLIMIT_STACK     resource to unlimited. (CVE-2016-3672)

  - The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) via vectors     involving omission of the firmware name from a certain     data structure. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely. (CVE-2016-7913)

  - Use-after-free vulnerability in the snd_pcm_info()     function in the ALSA subsystem in the Linux kernel     allows attackers to induce a kernel memory corruption     and possibly crash or lock up a system. Due to the     nature of the flaw, a privilege escalation cannot be     fully ruled out, although we believe it is unlikely.
    (CVE-2017-0861)

  - A reachable assertion failure flaw was found in the     Linux kernel built with KVM virtualisation(CONFIG_KVM)     support with Virtual Function I/O feature (CONFIG_VFIO)     enabled. This failure could occur if a malicious guest     device sent a virtual interrupt (guest IRQ) with a     larger (>1024) index value. (CVE-2017-1000252)

  - Linux kernel Virtualization Module (CONFIG_KVM) for the     Intel processor family (CONFIG_KVM_INTEL) is vulnerable     to a DoS issue. It could occur if a guest was to flood     the I/O port 0x80 with write requests. A guest user     could use this flaw to crash the host kernel resulting     in DoS. (CVE-2017-1000407)

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can be     sent to an attacker leaking data in kernel address     space. (CVE-2017-1000410)

  - A race condition was found in the Linux kernel before     version 4.11-rc1 in 'fs/timerfd.c' file which allows a     local user to cause a kernel list corruption or use-     after-free via simultaneous operations with a file     descriptor which leverage improper 'might_cancel'     queuing. An unprivileged local user could use this flaw     to cause a denial of service of the system. Due to the     nature of the flaw, privilege escalation cannot be fully     ruled out, although we believe it is unlikely.
    (CVE-2017-10661)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization (nVMX) feature     enabled (nested=1), is vulnerable to a crash due to     disabled external interrupts. As L2 guest could access     (r/w) hardware CR8 register of the host(L0). In a nested     visualization setup, L2 guest user could use this flaw     to potentially crash the host(L0) resulting in DoS.
    (CVE-2017-12154)

  - It was found that in the Linux kernel through v4.14-rc5,     bio_map_user_iov() and bio_unmap_user() in 'block/bio.c'     do unbalanced pages refcounting if IO vector has small     consecutive buffers belonging to the same page.
    bio_add_pc_page() merges them into one, but the page     reference is never dropped, causing a memory leak and     possible system lockup due to out-of-memory condition.
    (CVE-2017-12190)

  - A flaw was found in the Linux kernel's implementation of     valid_master_desc() in which a memory buffer would be     compared to a userspace value with an incorrect size of     comparison. By bruteforcing the comparison, an attacker     could determine what was in memory after the description     and possibly obtain sensitive information from kernel     memory. (CVE-2017-13305)

  - A use-after-free vulnerability was found in a network     namespaces code affecting the Linux kernel since     v4.0-rc1 through v4.15-rc5. The function     get_net_ns_by_id() does not check for the net::count     value after it has found a peer network in netns_ids idr     which could lead to double free and memory corruption.
    This vulnerability could allow an unprivileged local     user to induce kernel memory corruption on the system,     leading to a crash. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     it is thought to be unlikely. (CVE-2017-15129)

  - A use-after-free vulnerability was found when issuing an     ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption or     possibly privilege escalation. (CVE-2017-15265)

  - A flaw was found in the implementation of associative     arrays where the add_key systemcall and KEYCTL_UPDATE     operations allowed for a NULL payload with a nonzero     length. When accessing the payload within this length     parameters value, an unprivileged user could trivially     cause a NULL pointer dereference (kernel oops).
    (CVE-2017-15274)

  - The net/netfilter/nfnetlink_cthelper.c function in the     Linux kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for new, get, and del     operations. This allows local users to bypass intended     access restrictions because the nfnl_cthelper_list data     structure is shared across all net namespaces.
    (CVE-2017-17448)

  - The __netlink_deliver_tap_skb function in     net/netlink/af_netlink.c in the Linux kernel, through     4.14.4, does not restrict observations of Netlink     messages to a single net namespace, when CONFIG_NLMON is     enabled. This allows local users to obtain sensitive     information by leveraging the CAP_NET_ADMIN capability     to sniff an nlmon interface for all Netlink activity on     the system. (CVE-2017-17449)

  - The usb_destroy_configuration() function, in     'drivers/usb/core/config.c' in the USB core subsystem,     in the Linux kernel through 4.14.5 does not consider the     maximum number of configurations and interfaces before     attempting to release resources. This allows local users     to cause a denial of service, due to out-of-bounds write     access, or possibly have unspecified other impact via a     crafted USB device. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     we believe it is unlikely. (CVE-2017-17558)

  - The Salsa20 encryption algorithm in the Linux kernel,     before 4.14.8, does not correctly handle zero-length     inputs. This allows a local attacker the ability to use     the AF_ALG-based skcipher interface to cause a denial of     service (uninitialized-memory free and kernel crash) or     have an unspecified other impact by executing a crafted     sequence of system calls that use the blkcipher_walk     API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 are     vulnerable. (CVE-2017-17805)

  - The tcpmss_mangle_packet function in     net/netfilter/xt_TCPMSS.c in the Linux kernel before     4.11, and 4.9.x before 4.9.36, allows remote attackers     to cause a denial of service (use-after-free and memory     corruption) or possibly have unspecified other impact by     leveraging the presence of xt_TCPMSS in an iptables     action. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely. (CVE-2017-18017)

  - The Linux kernel, before version 4.14.3, is vulnerable     to a denial of service in     drivers/md/dm.c:dm_get_from_kobject() which can be     caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM     devices. Only privileged local users (with CAP_SYS_ADMIN     capability) can directly perform the ioctl operations     for dm device creation and removal and this would     typically be outside the direct control of the     unprivileged attacker. (CVE-2017-18203)

  - The madvise_willneed function in the Linux kernel allows     local users to cause a denial of service (infinite loop)     by triggering use of MADVISE_WILLNEED for a DAX mapping.
    (CVE-2017-18208)

  - A flaw was found where the kernel truncated the value     used to indicate the size of a buffer which it would     later become zero using an untruncated value. This can     corrupt memory outside of the original allocation.
    (CVE-2017-9725)

  - In the Linux kernel versions 4.12, 3.10, 2.6, and     possibly earlier, a race condition vulnerability exists     in the sound system allowing for a potential deadlock     and memory corruption due to use-after-free condition     and thus denial of service. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely. (CVE-2018-1000004)

  - Improper validation in the bnx2x network card driver of     the Linux kernel version 4.15 can allow for denial of     service (DoS) attacks via a packet with a gso_size     larger than ~9700 bytes. Untrusted guest VMs can exploit     this vulnerability in the host machine, causing a crash     in the network card. (CVE-2018-1000026)

  - By mmap()ing a FUSE-backed file onto a process's memory     containing command line arguments (or environment     strings), an attacker can cause utilities from psutils     or procps (such as ps, w) or any other program which     makes a read() call to the /proc//cmdline (or     /proc//environ) files to block indefinitely (denial     of service) or for some controlled time (as a     synchronization primitive for other attacks).
    (CVE-2018-1120)

  - A null pointer dereference in dccp_write_xmit() function     in net/dccp/output.c in the Linux kernel allows a local     user to cause a denial of service by a number of certain     crafted system calls. (CVE-2018-1130)

  - An issue was discovered in the proc_pid_stack function     in fs/proc/base.c in the Linux kernel. An attacker with     a local account can trick the stack unwinder code to     leak stack contents to userspace. The fix allows only     root to inspect the kernel stack of an arbitrary task.
    (CVE-2018-17972)

  - A flaw was found in the Linux kernel with files on tmpfs     and hugetlbfs. An attacker is able to bypass file     permissions on filesystems mounted with tmpfs/hugetlbs     to modify a file and possibly disrupt normal system     behavior. At this time there is an understanding there     is no crash or privilege escalation but the impact of     modifications on these filesystems of files in     production systems may have adverse affects.
    (CVE-2018-18397)

  - In the Linux kernel before 4.17, a local attacker able     to set attributes on an xfs filesystem could make this     filesystem non-operational until the next mount by     triggering an unchecked error condition during an xfs     attribute change, because xfs_attr_shortform_addname in     fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE     operations with conversion of an attr from short to long     form. (CVE-2018-18690)

  - A flaw was found in the Linux kernel's handling of     loopback devices. An attacker, who has permissions to     setup loopback disks, may create a denial of service or     other unspecified actions. (CVE-2018-5344)

  - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c     in the Linux kernel, through 4.14.15, allows local users     to obtain sensitive address information by reading dmesg     data from an SBS HC printk call. (CVE-2018-5750)

  - An error in the _sctp_make_chunk() function     (net/sctp/sm_make_chunk.c) when handling SCTP, packet     length can be exploited by a malicious local user to     cause a kernel crash and a DoS. (CVE-2018-5803)

  - In the function wmi_set_ie() in the Linux kernel the     length validation code does not handle unsigned integer     overflow properly. As a result, a large value of the     ie_len argument can cause a buffer overflow and thus a     memory corruption leading to a system crash or other or     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     we believe it is unlikely. (CVE-2018-5848)

  - ALSA sequencer core initializes the event pool on demand     by invoking snd_seq_pool_init() when the first write     happens and the pool is empty. A user can reset the pool     size manually via ioctl concurrently, and this may lead     to UAF or out-of-bound access. (CVE-2018-7566)

  - A possible memory corruption due to a type confusion was     found in the Linux kernel in the sk_clone_lock()     function in the net/core/sock.c. The possibility of     local escalation of privileges cannot be fully ruled out     for a local unprivileged attacker. (CVE-2018-9568)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - Integer overflow in the aio_setup_single_vector function     in fs/aio.c in the Linux kernel 4.0 allows local users     to cause a denial of service or possibly have     unspecified other impact via a large AIO iovec. NOTE:
    this vulnerability exists because of a CVE-2012-6701     regression. (CVE-2015-8830)

  - A weakness was found in the Linux ASLR implementation.
    Any user able to running 32-bit applications in a x86     machine can disable ASLR by setting the RLIMIT_STACK     resource to unlimited. (CVE-2016-3672)

  - The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) via vectors     involving omission of the firmware name from a certain     data structure. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely. (CVE-2016-7913)

  - Use-after-free vulnerability in the snd_pcm_info()     function in the ALSA subsystem in the Linux kernel     allows attackers to induce a kernel memory corruption     and possibly crash or lock up a system. Due to the     nature of the flaw, a privilege escalation cannot be     fully ruled out, although we believe it is unlikely.
    (CVE-2017-0861)

  - A reachable assertion failure flaw was found in the     Linux kernel built with KVM virtualisation(CONFIG_KVM)     support with Virtual Function I/O feature (CONFIG_VFIO)     enabled. This failure could occur if a malicious guest     device sent a virtual interrupt (guest IRQ) with a     larger (>1024) index value. (CVE-2017-1000252)

  - Linux kernel Virtualization Module (CONFIG_KVM) for the     Intel processor family (CONFIG_KVM_INTEL) is vulnerable     to a DoS issue. It could occur if a guest was to flood     the I/O port 0x80 with write requests. A guest user     could use this flaw to crash the host kernel resulting     in DoS. (CVE-2017-1000407)

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can be     sent to an attacker leaking data in kernel address     space. (CVE-2017-1000410)

  - A race condition was found in the Linux kernel before     version 4.11-rc1 in 'fs/timerfd.c' file which allows a     local user to cause a kernel list corruption or use-     after-free via simultaneous operations with a file     descriptor which leverage improper 'might_cancel'     queuing. An unprivileged local user could use this flaw     to cause a denial of service of the system. Due to the     nature of the flaw, privilege escalation cannot be fully     ruled out, although we believe it is unlikely.
    (CVE-2017-10661)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization (nVMX) feature     enabled (nested=1), is vulnerable to a crash due to     disabled external interrupts. As L2 guest could access     (r/w) hardware CR8 register of the host(L0). In a nested     visualization setup, L2 guest user could use this flaw     to potentially crash the host(L0) resulting in DoS.
    (CVE-2017-12154)

  - It was found that in the Linux kernel through v4.14-rc5,     bio_map_user_iov() and bio_unmap_user() in 'block/bio.c'     do unbalanced pages refcounting if IO vector has small     consecutive buffers belonging to the same page.
    bio_add_pc_page() merges them into one, but the page     reference is never dropped, causing a memory leak and     possible system lockup due to out-of-memory condition.
    (CVE-2017-12190)

  - A flaw was found in the Linux kernel's implementation of     valid_master_desc() in which a memory buffer would be     compared to a userspace value with an incorrect size of     comparison. By bruteforcing the comparison, an attacker     could determine what was in memory after the description     and possibly obtain sensitive information from kernel     memory. (CVE-2017-13305)

  - A use-after-free vulnerability was found in a network     namespaces code affecting the Linux kernel since     v4.0-rc1 through v4.15-rc5. The function     get_net_ns_by_id() does not check for the net::count     value after it has found a peer network in netns_ids idr     which could lead to double free and memory corruption.
    This vulnerability could allow an unprivileged local     user to induce kernel memory corruption on the system,     leading to a crash. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     it is thought to be unlikely. (CVE-2017-15129)

  - A use-after-free vulnerability was found when issuing an     ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption or     possibly privilege escalation. (CVE-2017-15265)

  - A flaw was found in the implementation of associative     arrays where the add_key systemcall and KEYCTL_UPDATE     operations allowed for a NULL payload with a nonzero     length. When accessing the payload within this length     parameters value, an unprivileged user could trivially     cause a NULL pointer dereference (kernel oops).
    (CVE-2017-15274)

  - The net/netfilter/nfnetlink_cthelper.c function in the     Linux kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for new, get, and del     operations. This allows local users to bypass intended     access restrictions because the nfnl_cthelper_list data     structure is shared across all net namespaces.
    (CVE-2017-17448)

  - The __netlink_deliver_tap_skb function in     net/netlink/af_netlink.c in the Linux kernel, through     4.14.4, does not restrict observations of Netlink     messages to a single net namespace, when CONFIG_NLMON is     enabled. This allows local users to obtain sensitive     information by leveraging the CAP_NET_ADMIN capability     to sniff an nlmon interface for all Netlink activity on     the system. (CVE-2017-17449)

  - The usb_destroy_configuration() function, in     'drivers/usb/core/config.c' in the USB core subsystem,     in the Linux kernel through 4.14.5 does not consider the     maximum number of configurations and interfaces before     attempting to release resources. This allows local users     to cause a denial of service, due to out-of-bounds write     access, or possibly have unspecified other impact via a     crafted USB device. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     we believe it is unlikely. (CVE-2017-17558)

  - The Salsa20 encryption algorithm in the Linux kernel,     before 4.14.8, does not correctly handle zero-length     inputs. This allows a local attacker the ability to use     the AF_ALG-based skcipher interface to cause a denial of     service (uninitialized-memory free and kernel crash) or     have an unspecified other impact by executing a crafted     sequence of system calls that use the blkcipher_walk     API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 are     vulnerable. (CVE-2017-17805)

  - The tcpmss_mangle_packet function in     net/netfilter/xt_TCPMSS.c in the Linux kernel before     4.11, and 4.9.x before 4.9.36, allows remote attackers     to cause a denial of service (use-after-free and memory     corruption) or possibly have unspecified other impact by     leveraging the presence of xt_TCPMSS in an iptables     action. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely. (CVE-2017-18017)

  - The Linux kernel, before version 4.14.3, is vulnerable     to a denial of service in     drivers/md/dm.c:dm_get_from_kobject() which can be     caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM     devices. Only privileged local users (with CAP_SYS_ADMIN     capability) can directly perform the ioctl operations     for dm device creation and removal and this would     typically be outside the direct control of the     unprivileged attacker. (CVE-2017-18203)

  - The madvise_willneed function in the Linux kernel allows     local users to cause a denial of service (infinite loop)     by triggering use of MADVISE_WILLNEED for a DAX mapping.
    (CVE-2017-18208)

  - A flaw was found where the kernel truncated the value     used to indicate the size of a buffer which it would     later become zero using an untruncated value. This can     corrupt memory outside of the original allocation.
    (CVE-2017-9725)

  - In the Linux kernel versions 4.12, 3.10, 2.6, and     possibly earlier, a race condition vulnerability exists     in the sound system allowing for a potential deadlock     and memory corruption due to use-after-free condition     and thus denial of service. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely. (CVE-2018-1000004)

  - Improper validation in the bnx2x network card driver of     the Linux kernel version 4.15 can allow for denial of     service (DoS) attacks via a packet with a gso_size     larger than ~9700 bytes. Untrusted guest VMs can exploit     this vulnerability in the host machine, causing a crash     in the network card. (CVE-2018-1000026)

  - By mmap()ing a FUSE-backed file onto a process's memory     containing command line arguments (or environment     strings), an attacker can cause utilities from psutils     or procps (such as ps, w) or any other program which     makes a read() call to the /proc//cmdline (or     /proc//environ) files to block indefinitely (denial     of service) or for some controlled time (as a     synchronization primitive for other attacks).
    (CVE-2018-1120)

  - A null pointer dereference in dccp_write_xmit() function     in net/dccp/output.c in the Linux kernel allows a local     user to cause a denial of service by a number of certain     crafted system calls. (CVE-2018-1130)

  - An issue was discovered in the proc_pid_stack function     in fs/proc/base.c in the Linux kernel. An attacker with     a local account can trick the stack unwinder code to     leak stack contents to userspace. The fix allows only     root to inspect the kernel stack of an arbitrary task.
    (CVE-2018-17972)

  - A flaw was found in the Linux kernel with files on tmpfs     and hugetlbfs. An attacker is able to bypass file     permissions on filesystems mounted with tmpfs/hugetlbs     to modify a file and possibly disrupt normal system     behavior. At this time there is an understanding there     is no crash or privilege escalation but the impact of     modifications on these filesystems of files in     production systems may have adverse affects.
    (CVE-2018-18397)

  - In the Linux kernel before 4.17, a local attacker able     to set attributes on an xfs filesystem could make this     filesystem non-operational until the next mount by     triggering an unchecked error condition during an xfs     attribute change, because xfs_attr_shortform_addname in     fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE     operations with conversion of an attr from short to long     form. (CVE-2018-18690)

  - Modern operating systems implement virtualization of     physical memory to efficiently use available system     resources and provide inter-domain protection through     access control and isolation. The L1TF issue was found     in the way the x86 microprocessor designs have     implemented speculative execution of instructions (a     commonly used performance optimization) in combination     with handling of page-faults caused by terminated     virtual to physical address resolving process. As a     result, an unprivileged attacker could use this flaw to     read privileged memory of the kernel or other processes     and/or cross guest/host boundaries to read host memory     by conducting targeted cache side-channel attacks.
    (CVE-2018-3646)

  - A flaw was found in the Linux kernel's handling of     loopback devices. An attacker, who has permissions to     setup loopback disks, may create a denial of service or     other unspecified actions. (CVE-2018-5344)

  - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c     in the Linux kernel, through 4.14.15, allows local users     to obtain sensitive address information by reading dmesg     data from an SBS HC printk call. (CVE-2018-5750)

  - An error in the _sctp_make_chunk() function     (net/sctp/sm_make_chunk.c) when handling SCTP, packet     length can be exploited by a malicious local user to     cause a kernel crash and a DoS. (CVE-2018-5803)

  - In the function wmi_set_ie() in the Linux kernel the     length validation code does not handle unsigned integer     overflow properly. As a result, a large value of the     ie_len argument can cause a buffer overflow and thus a     memory corruption leading to a system crash or other or     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out, although     we believe it is unlikely. (CVE-2018-5848)

  - ALSA sequencer core initializes the event pool on demand     by invoking snd_seq_pool_init() when the first write     happens and the pool is empty. A user can reset the pool     size manually via ioctl concurrently, and this may lead     to UAF or out-of-bound access. (CVE-2018-7566)

  - A possible memory corruption due to a type confusion was     found in the Linux kernel in the sk_clone_lock()     function in the net/core/sock.c. The possibility of     local escalation of privileges cannot be fully ruled out     for a local unprivileged attacker. (CVE-2018-9568)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-4644 advisory.

    - Input: wacom - move the USB (now hid) Wacom driver in drivers/hid (Benjamin Tissoires)  [Orabug:

    - KEYS: encrypted: fix buffer overread in valid_master_desc() (Eric Biggers)  [Orabug: 29605993]     {CVE-2017-13305}
    - ecryptfs: don't allow mmap when the lower fs doesn't support it (Jeff Mahoney)  [Orabug: 29666607]     {CVE-2016-1583} {CVE-2016-1583}
    - Revert 'ecryptfs: forbid opening files without mmap handler' (Brian Maly)  [Orabug: 29666607]     {CVE-2016-1583}

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The function hso_get_config_data in     drivers/net/usb/hso.c in the Linux kernel through     4.19.8 reads if_num from the USB device (as a u8) and     uses it to index a small array, resulting in an object     out-of-bounds (OOB) read that potentially allows     arbitrary read in the kernel address     space.(CVE-2018-19985)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5754 relies on the     fact that, on impacted microprocessors, during     speculative execution of instruction permission faults,     exception generation triggered by a faulting access is     suppressed until the retirement of the whole     instruction block. In a combination with the fact that     memory accesses may populate the cache even when the     block is being dropped and never committed (executed),     an unprivileged local attacker could use this flaw to     read privileged (kernel space) memory by conducting     targeted cache side-channel attacks. Note:
    CVE-2017-5754 affects Intel x86-64 microprocessors. AMD     x86-64 microprocessors are not affected by this     issue.(CVE-2017-5754)

  - A non-privileged user is able to mount a fuse     filesystem on RHEL 6 or 7 and crash a system if an     application punches a hole in a file that does not end     aligned to a page boundary.(CVE-2017-15121)

  - A flaw was found in the Linux kernel when attempting to     'punch a hole' in files existing on an ext4 filesystem.
    When punching holes into a file races with the page     fault of the same area, it is possible that freed     blocks remain referenced from page cache pages mapped     to process' address space.(CVE-2015-8839)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions past bounds check. The flaw     relies on the presence of a precisely-defined     instruction sequence in the privileged code and the     fact that memory writes occur to an address which     depends on the untrusted value. Such writes cause an     update into the microprocessor's data cache even for     speculatively executed instructions that never actually     commit (retire). As a result, an unprivileged attacker     could use this flaw to influence speculative execution     and/or read privileged memory by conducting targeted     cache side-channel attacks.(CVE-2018-3693)

  - A Floating Point Unit (FPU) state information leakage     flaw was found in the way the Linux kernel saved and     restored the FPU state during task switch. Linux     kernels that follow the 'Lazy FPU Restore' scheme are     vulnerable to the FPU state information leakage issue.
    An unprivileged local attacker could use this flaw to     read FPU state bits by conducting targeted cache     side-channel attacks, similar to the Meltdown     vulnerability disclosed earlier this     year.(CVE-2018-3665)

  - A bug in the 32-bit compatibility layer of the ioctl     handling code of the v4l2 video driver in the Linux     kernel has been found. A memory protection mechanism     ensuring that user-provided buffers always point to a     userspace memory were disabled, allowing destination     address to be in a kernel space. This flaw could be     exploited by an attacker to overwrite a kernel memory     from an unprivileged userspace process, leading to     privilege escalation.(CVE-2017-13166)

  - It was found that the raw midi kernel driver does not     protect against concurrent access which leads to a     double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation.(CVE-2018-10902)

  - A flaw was found in the Linux kernel's implementation     of valid_master_desc() in which a memory buffer would     be compared to a userspace value with an incorrect size     of comparison. By bruteforcing the comparison, an     attacker could determine what was in memory after the     description and possibly obtain sensitive information     from kernel memory.(CVE-2017-13305)

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound write in in     fs/jbd2/transaction.c code, a denial of service, and a     system crash by unmounting a crafted ext4 filesystem     image.(CVE-2018-10882)

    - KEYS: encrypted: fix buffer overread in valid_master_desc() (Eric Biggers)  [Orabug: 29591025]     {CVE-2017-13305}

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The linux update issued as DLA-1731-1 caused a regression in the vmxnet3 (VMware virtual network adapter) driver. This update corrects that regression, and an earlier regression in the CIFS network filesystem implementation introduced in DLA-1422-1. For reference the original advisory text follows.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2016-10741

A race condition was discovered in XFS that would result in a crash (BUG). A local user permitted to write to an XFS volume could use this for denial of service.

CVE-2017-5753

Further instances of code that was vulnerable to Spectre variant 1 (bounds-check bypass) have been mitigated.

CVE-2017-13305

A memory over-read was discovered in the keys subsystem's encrypted key type. A local user could use this for denial of service or possibly to read sensitive information.

CVE-2018-3639 (SSB)

Multiple researchers have discovered that Speculative Store Bypass (SSB), a feature implemented in many processors, could be used to read sensitive information from another context. In particular, code in a software sandbox may be able to read sensitive information from outside the sandbox. This issue is also known as Spectre variant 4.

This update fixes bugs in the mitigations for SSB for AMD processors.

CVE-2018-5848

The wil6210 wifi driver did not properly validate lengths in scan and connection requests, leading to a possible buffer overflow. On systems using this driver, a local user with the CAP_NET_ADMIN capability could use this for denial of service (memory corruption or crash) or potentially for privilege escalation.

CVE-2018-5953

The swiotlb subsystem printed kernel memory addresses to the system log, which could help a local attacker to exploit other vulnerabilities.

CVE-2018-12896, CVE-2018-13053

Team OWL337 reported possible integer overflows in the POSIX timer implementation. These might have some security impact.

CVE-2018-16862

Vasily Averin and Pavel Tikhomirov from Virtuozzo Kernel Team discovered that the cleancache memory management feature did not invalidate cached data for deleted files. On Xen guests using the tmem driver, local users could potentially read data from other users' deleted files if they were able to create new files on the same volume.

CVE-2018-16884

A flaw was found in the NFS 4.1 client implementation. Mounting NFS shares in multiple network namespaces at the same time could lead to a user-after-free. Local users might be able to use this for denial of service (memory corruption or crash) or possibly for privilege escalation.

This can be mitigated by disabling unprivileged users from creating user namespaces, which is the default in Debian.

CVE-2018-17972

Jann Horn reported that the /proc/*/stack files in procfs leaked sensitive data from the kernel. These files are now only readable by users with the CAP_SYS_ADMIN capability (usually only root)

CVE-2018-18281

Jann Horn reported a race condition in the virtual memory manager that can result in a process briefly having access to memory after it is freed and reallocated. A local user permitted to create containers could possibly exploit this for denial of service (memory corruption) or for privilege escalation.

CVE-2018-18690

Kanda Motohiro reported that XFS did not correctly handle some xattr (extended attribute) writes that require changing the disk format of the xattr. A user with access to an XFS volume could use this for denial of service.

CVE-2018-18710

It was discovered that the cdrom driver does not correctly validate the parameter to the CDROM_SELECT_DISC ioctl. A user with access to a cdrom device could use this to read sensitive information from the kernel or to cause a denial of service (crash).

CVE-2018-19824

Hui Peng and Mathias Payer discovered a use-after-free bug in the USB audio driver. A physically present attacker able to attach a specially designed USB device could use this for privilege escalation.

CVE-2018-19985

CVE-2018-20169

Hui Peng and Mathias Payer discovered missing bounds checks in the USB core. A physically present attacker able to attach a specially designed USB device could use this to cause a denial of service (crash) or possibly for privilege escalation.

CVE-2018-20511

InfoSect reported an information leak in the AppleTalk IP/DDP implemntation. A local user with CAP_NET_ADMIN capability could use this to read sensitive information from the kernel.

CVE-2019-3701

Muyu Yu and Marcus Meissner reported that the CAN gateway implementation allowed the frame length to be modified, typically resulting in out-of-bounds memory-mapped I/O writes. On a system with CAN devices present, a local user with CAP_NET_ADMIN capability in the initial net namespace could use this to cause a crash (oops) or other hardware-dependent impact.

CVE-2019-3819

A potential infinite loop was discovered in the HID debugfs interface exposed under /sys/kernel/debug/hid. A user with access to these files could use this for denial of service.

This interface is only accessible to root by default, which fully mitigates the issue.

CVE-2019-6974

Jann Horn reported a use-after-free bug in KVM. A local user with access to /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-7221

Jim Mattson and Felix Wilhelm reported a user-after-free bug in KVM's nested VMX implementation. On systems with Intel CPUs, a local user with access to /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

Nested VMX is disabled by default, which fully mitigates the issue.

CVE-2019-7222

Felix Wilhelm reported an information leak in KVM for x86. A local user with access to /dev/kvm could use this to read sensitive information from the kernel.

CVE-2019-9213

Jann Horn reported that privileged tasks could cause stack segments, including those in other processes, to grow downward to address 0. On systems lacking SMAP (x86) or PAN (ARM), this exacerbated other vulnerabilities: a NULL pointer dereference could be exploited for privilege escalation rather than only for denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 3.16.64-1.

We recommend that you upgrade your linux packages.
