According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The NFSv2 and NFSv3 server implementations in the Linux     kernel through 4.10.13 lacked certain checks for the     end of a buffer. A remote attacker could trigger a     pointer-arithmetic error or possibly cause other     unspecified impacts using crafted requests related to     fs/nfsd/nfs3xdr.c and     fs/nfsd/nfsxdr.c.(CVE-2017-7895i1/4%0

  - A flaw was found in the Linux kernel's ACPI subsystem     where a function does not flush the operand cache and     causes a kernel stack dump. This allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism when using a     specially crafted ACPI table.(CVE-2017-13695i1/4%0

  - It was found that fanout_add() in     'net/packet/af_packet.c' in the Linux kernel, before     version 4.13.6, allows local users to gain privileges     via crafted system calls that trigger mishandling of     packet_fanout data structures, because of a race     condition (involving fanout_add and packet_do_bind)     that leads to a use-after-free bug.(CVE-2017-15649i1/4%0

  - Race condition in kernel/ucount.c in the Linux kernel     through 4.10.2 allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via crafted system calls     that leverage certain decrement behavior that causes     incorrect interaction between put_ucounts and     get_ucounts.(CVE-2017-6874i1/4%0

  - An out-of-bounds memory access flaw, CVE-2014-7825, was     found in the syscall tracing functionality of the Linux     kernel's perf subsystem. A local, unprivileged user     could use this flaw to crash the system. Additionally,     an out-of-bounds memory access flaw, CVE-2014-7826, was     found in the syscall tracing functionality of the Linux     kernel's ftrace subsystem. On a system with ftrace     syscall tracing enabled, a local, unprivileged user     could use this flaw to crash the system, or escalate     their privileges.(CVE-2014-7825i1/4%0

  - 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-2017-17805i1/4%0

  - The msm_ipc_router_bind_control_port function in     net/ipc_router/ipc_router_core.c in the IPC router     kernel module for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, does not verify     that a port is a client port, which allows attackers to     gain privileges or cause a denial of service (race     condition and list corruption) by making many     BIND_CONTROL_PORT ioctl calls.(CVE-2016-2059i1/4%0

  - The do_remount function in fs/namespace.c in the Linux     kernel through 3.16.1 does not maintain the     MNT_LOCK_READONLY bit across a remount of a bind mount,     which allows local users to bypass an intended     read-only restriction and defeat certain sandbox     protection mechanisms via a 'mount -o remount' command     within a user namespace.(CVE-2014-5206i1/4%0

  - The ati_remote2_probe function in     drivers/input/misc/ati_remote2.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2185i1/4%0

  - It was found that the fix for CVE-2014-3601 was     incomplete: the Linux kernel's kvm_iommu_map_pages()     function still handled IOMMU mapping failures     incorrectly. A privileged user in a guest with an     assigned host device could use this flaw to crash the     host.(CVE-2014-8369i1/4%0

  - A NULL pointer dereference was found in     net/rds/rdma.c:__rds_rdma_map() function in the Linux     kernel allowing local attackers to cause a system panic     and a denial-of-service.(CVE-2018-7492i1/4%0

  - An issue was discovered in the XFS filesystem in     fs/xfs/xfs_icache.c in the Linux kernel. There is a     NULL pointer dereference leading to a system panic in     lookup_slow() on a NULL inode-i1/4zi_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 an allocation.(CVE-2018-13093i1/4%0

  - The iowarrior_probe function in     drivers/usb/misc/iowarrior.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a crafted endpoints value in a USB device     descriptor.(CVE-2016-2188i1/4%0

  - Linux kernel built with the 802.1Q/802.1ad     VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local     Area Network(CONFIG_VXLAN) with Transparent Ethernet     Bridging(TEB) GRO support, is vulnerable to a stack     overflow issue. It could occur while receiving large     packets via GRO path, as an unlimited recursion could     unfold in both VLAN and TEB modules, leading to a stack     corruption in the kernel.(CVE-2016-7039i1/4%0

  - The msr_mtrr_valid function in arch/x86/kvm/mtrr.c in     the Linux kernel before 4.6.1 supports MSR 0x2f8, which     allows guest OS users to read or write to the     kvm_arch_vcpu data structure, and consequently obtain     sensitive information or cause a denial of service     (system crash), via a crafted ioctl     call.(CVE-2016-3713i1/4%0

  - A flaw was found in the way the Linux kernel's VFS     subsystem handled reference counting when performing     unmount operations on symbolic links. A local,     unprivileged user could use this flaw to exhaust all     available memory on the system or, potentially, trigger     a use-after-free error, resulting in a system crash or     privilege escalation.(CVE-2014-5045i1/4%0

  - The KEYS subsystem in the Linux kernel before 4.13.10     does not correctly synchronize the actions of updating     versus finding a key in the 'negative' state to avoid a     race condition, which allows local users to cause a     denial of service or possibly have unspecified other     impact via crafted system calls.(CVE-2017-15951i1/4%0

  - The skb_flow_dissect function in     net/core/flow_dissector.c in the Linux kernel through     3.12 allows remote attackers to cause a denial of     service (infinite loop) via a small value in the IHL     field of a packet with IPIP     encapsulation.(CVE-2013-4348i1/4%0

  - The Linux kernel through 3.17.4 does not properly     restrict dropping of supplemental group memberships in     certain namespace scenarios, which allows local users     to bypass intended file permissions by leveraging a     POSIX ACL containing an entry for the group category     that is more restrictive than the entry for the other     category, aka a 'negative groups' issue, related to     kernel/groups.c, kernel/uid16.c, and     kernel/user_namespace.c.(CVE-2014-8989i1/4%0

  - An infinite-loop flaw was found in the kernel. When a     local user calls the sys_writev syscall with a     specially crafted sequence of iov structs, the     fuse_fill_write_pages kernel function might never     terminate, instead continuing in a tight loop. This     process cannot be terminated and requires a     reboot.(CVE-2015-8785i1/4%0

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.

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

  - An information-leak vulnerability was found in the     kernel when it truncated a file to a smaller size which     consisted of an inline extent that was compressed. The     data between the new file size and the old file size     was not discarded and the number of bytes used by the     inode were not correctly decremented, which gave the     wrong report for callers of the stat(2) syscall. This     wasted metadata space and allowed for the truncated     data to be leaked, and data corruption or loss to     occur. A caller of the clone ioctl could exploit this     flaw by using only standard file-system operations     without root access to read the truncated     data.(CVE-2015-8374)

  - A flaw was found in the Linux kernel's key management     system where it was possible for an attacker to     escalate privileges or crash the machine. If a user key     gets negatively instantiated, an error code is cached     in the payload area. A negatively instantiated key may     be then be positively instantiated by updating it with     valid data. However, the -i1/4zupdate key type method     must be aware that the error code may be     there.(CVE-2015-8539)

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's network subsystem handled socket     creation with an invalid protocol identifier. A local     user could use this flaw to crash the     system.(CVE-2015-8543)

  - An out-of-bounds flaw was found in the kernel, where     the length of the sockaddr parameter was not checked in     the pptp_bind() and pptp_connect() functions. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local system user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8569)

  - An out-of-bounds flaw was found in the kernel, where     the sco_sock_bind() function (bluetooth/sco) did not     check the length of its sockaddr parameter. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8575)

  - The ovl_setattr function in fs/overlayfs/inode.c in the     Linux kernel through 4.3.3 attempts to merge distinct     setattr operations, which allows local users to bypass     intended access restrictions and modify the attributes     of arbitrary overlay files via a crafted     application.(CVE-2015-8660)

  - A NULL pointer dereference flaw was found in the Linux     kernel: the NFSv4.2 migration code improperly     initialized the kernel structure. A local,     authenticated user could use this flaw to cause a panic     of the NFS client (denial of service).(CVE-2015-8746)

  - A race condition flaw was found in the way the Linux     kernel's SCTP implementation handled sctp_accept()     during the processing of heartbeat timeout events. A     remote attacker could use this flaw to prevent further     connections to be accepted by the SCTP server running     on the system, resulting in a denial of     service.(CVE-2015-8767)

  - An infinite-loop flaw was found in the kernel. When a     local user calls the sys_writev syscall with a     specially crafted sequence of iov structs, the     fuse_fill_write_pages kernel function might never     terminate, instead continuing in a tight loop. This     process cannot be terminated and requires a     reboot.(CVE-2015-8785)

  - A NULL-pointer dereference vulnerability was found in     the Linux kernel's TCP stack, in     net/netfilter/nf_nat_redirect.c in the     nf_nat_redirect_ipv4() function. A remote,     unauthenticated user could exploit this flaw to create     a system crash (denial of service).(CVE-2015-8787)

  - A use-after-free flaw was found in the CXGB3 kernel     driver when the network was considered to be congested.
    The kernel incorrectly misinterpreted the congestion as     an error condition and incorrectly freed or cleaned up     the socket buffer (skb). When the device then sent the     skb's queued data, these structures were referenced. A     local attacker could use this flaw to panic the system     (denial of service) or, with a local account, escalate     their privileges.(CVE-2015-8812)

  - The hub_activate function in drivers/usb/core/hub.c in     the Linux kernel before 4.3.5 does not properly     maintain a hub-interface data structure, which allows     physically proximate attackers to cause a denial of     service (invalid memory access and system crash) or     possibly have unspecified other impact by unplugging a     USB hub device.(CVE-2015-8816)

  - The ioresources_init function in kernel/resource.c in     the Linux kernel through 4.7, as used in Android before     2016-08-05 on Nexus 6 and 7 (2013) devices, uses weak     permissions for /proc/iomem, which allows local users     to obtain sensitive information by reading this file,     aka Android internal bug 28814213 and Qualcomm internal     bug CR786116. NOTE: the permissions may be intentional     in most non-Android contexts.(CVE-2015-8944)

  - 'A flaw was found in the Linux kernel's implementation     of overlayfs. An attacker can leak file resources in     the system by opening a large file with write     permissions on a overlay filesystem that is     insufficient to deal with the size of the write.

  - When unmounting the underlying device, the system is     unable to free an inode and this will consume     resources. Repeating this for all available inodes and     memory will create a denial of service     situation.(CVE-2015-8953)'

  - The rfcomm_sock_bind function in     net/bluetooth/rfcomm/sock.c in the Linux kernel before     4.2 allows local users to obtain sensitive information     or cause a denial of service (NULL pointer dereference)     via vectors involving a bind system call on a Bluetooth     RFCOMM socket.(CVE-2015-8956)

  - A flaw was found in the ext4 subsystem. This     vulnerability is a use after free vulnerability was     found in __ext4_journal_stop(). Attackers could abuse     this to allow any code which attempts to deal with the     journal failure to be mishandled or not fail at all.
    This could lead to data corruption or     crashes.(CVE-2015-8961)

  - A flaw was found in the Linux kernel SCSI subsystem,     which allowed a local user to gain privileges or cause     a denial of service (memory corruption and system     crash) by issuing an SG_IO ioctl call while a device     was being detached.(CVE-2015-8962)

  - Race condition in kernel/events/core.c in the Linux     kernel before 4.4 allows local users to gain privileges     or cause a denial of service via use-after-free     vulnerability by leveraging incorrect handling of an     swevent data structure during a CPU unplug     operation.(CVE-2015-8963)

  - The tty_set_termios_ldisc() function in     'drivers/tty/tty_ldisc.c' in the Linux kernel before     4.5 allows local users to obtain sensitive information     from kernel memory by reading a tty data     structure.(CVE-2015-8964)

  - The lrw_crypt() function in 'crypto/lrw.c' in the Linux     kernel before 4.5 allows local users to cause a system     crash and a denial of service by the NULL pointer     dereference via accept(2) system call for AF_ALG socket     without calling setkey() first to set a cipher     key.(CVE-2015-8970)

  - It was found that kernel/events/core.c in the Linux     kernel mishandles counter grouping, which allows local     users to gain privileges via a crafted application,     related to the perf_pmu_register and perf_event_open     functions.(CVE-2015-9004)

  - A use-after-free flaw was discovered in the Linux     kernel's tty subsystem, which allows for the disclosure     of uncontrolled memory location and possible kernel     panic. The information leak is caused by a race     condition when attempting to set and read the tty line     discipline. A local attacker could use the TIOCSETD     (via tty_set_ldisc ) to switch to a new line discipline     a concurrent call to a TIOCGETD ioctl performing a read     on a given tty could then access previously allocated     memory. Up to 4 bytes could be leaked when querying the     line discipline or the kernel could panic with a     NULL-pointer dereference.(CVE-2016-0723)

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 following security bugs were fixed :

  - CVE-2015-1339: A memory leak in cuse could be used to     exhaust kernel memory. (bsc#969356).

  - CVE-2015-7799: The slhc_init function in     drivers/net/slip/slhc.c in the Linux kernel did not     ensure that certain slot numbers are valid, which     allowed local users to cause a denial of service (NULL     pointer dereference and system crash) via a crafted     PPPIOCSMAXCID ioctl call (bnc#949936 951638).

  - CVE-2015-7872: The key_gc_unused_keys function in     security/keys/gc.c in the Linux kernel allowed local     users to cause a denial of service (OOPS) via crafted     keyctl commands (bnc#951440).

  - CVE-2015-7884: The vivid_fb_ioctl function in     drivers/media/platform/vivid/vivid-osd.c in the Linux     kernel did not initialize a certain structure member,     which allowed local users to obtain sensitive     information from kernel memory via a crafted application     (bnc#951626).

  - CVE-2015-8104: The KVM subsystem in the Linux kernel     allowed guest OS users to cause a denial of service     (host OS panic or hang) by triggering many #DB (aka     Debug) exceptions, related to svm.c (bnc#954404).

  - CVE-2015-8709: kernel/ptrace.c in the Linux kernel     mishandled uid and gid mappings, which allowed local     users to gain privileges by establishing a user     namespace, waiting for a root process to enter that     namespace with an unsafe uid or gid, and then using the     ptrace system call. NOTE: the vendor states 'there is no     kernel bug here (bnc#959709).

  - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux     kernel did not properly manage the relationship between     a lock and a socket, which allowed local users to cause     a denial of service (deadlock) via a crafted sctp_accept     call. (bsc#961509)

  - CVE-2015-8785: The fuse_fill_write_pages function in     fs/fuse/file.c in the Linux kernel allowed local users     to cause a denial of service (infinite loop) via a     writev system call that triggers a zero length for the     first segment of an iov (bnc#963765).

  - CVE-2015-8787: The nf_nat_redirect_ipv4 function in     net/netfilter/nf_nat_redirect.c in the Linux kernel     allowed remote attackers to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact by sending certain IPv4     packets to an incompletely configured interface, a     related issue to CVE-2003-1604 (bnc#963931).

  - CVE-2015-8812: A flaw was found in the CXGB3 kernel     driver when the network was considered congested. The     kernel would incorrectly misinterpret the congestion as     an error condition and incorrectly free/clean up the     skb. When the device would then send the skb's queued,     these structures would be referenced and may panic the     system or allow an attacker to escalate privileges in a     use-after-free scenario. (bsc#966437).

  - CVE-2016-0723: Race condition in the tty_ioctl function     in drivers/tty/tty_io.c in the Linux kernel allowed     local users to obtain sensitive information from kernel     memory or cause a denial of service (use-after-free and     system crash) by making a TIOCGETD ioctl call during     processing of a TIOCSETD ioctl call (bnc#961500).

  - CVE-2016-2069: When Linux invalidated a paging structure     that is not in use locally, it could, in principle, race     against another CPU that is switching to a process that     uses the paging structure in question. (bsc#963767)

  - CVE-2015-8785: The fuse_fill_write_pages function in     fs/fuse/file.c in the Linux kernel allowed local users     to cause a denial of service (infinite loop) via a     writev system call that triggers a zero length for the     first segment of an iov (bnc#963765).

  - CVE-2015-8812: A use-after-free flaw was found in the     CXGB3 kernel driver when the network was considered to     be congested. This could be used by local attackers to     cause machine crashes or potentially code executuon     (bsc#966437).

  - CVE-2016-0723: Race condition in the tty_ioctl function     in drivers/tty/tty_io.c in the Linux kernel allowed     local users to obtain sensitive information from kernel     memory or cause a denial of service (use-after-free and     system crash) by making a TIOCGETD ioctl call during     processing of a TIOCSETD ioctl call (bnc#961500).

  - CVE-2016-0774: A pipe buffer state corruption after     unsuccessful atomic read from pipe was fixed     (bsc#964730).

  - CVE-2016-2069: Race conditions in TLB syncing was fixed     which could leak to information leaks (bnc#963767).

  - CVE-2016-2384: A double-free triggered by invalid USB     descriptor in ALSA usb-audio was fixed, which could be     exploited by physical local attackers to crash the     kernel or gain code execution (bnc#966693).

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

  - CVE-2013-4312, CVE-2016-2847     Tetsuo Handa discovered that users can use pipes queued     on local (Unix) sockets to allocate an unfair share of     kernel memory, leading to denial-of-service (resource     exhaustion).

  This issue was previously mitigated for the stable suite by limiting   the total number of files queued by each user on local sockets. The   new kernel version in both suites includes that mitigation plus   limits on the total size of pipe buffers allocated for each user.

  - CVE-2015-7566     Ralf Spenneberg of OpenSource Security reported that the     visor driver crashes when a specially crafted USB device     without bulk-out endpoint is detected.

  - CVE-2015-8767     An SCTP denial-of-service was discovered which can be     triggered by a local attacker during a heartbeat timeout     event after the 4-way handshake.

  - CVE-2015-8785     It was discovered that local users permitted to write to     a file on a FUSE filesystem could cause a denial of     service (unkillable loop in the kernel).

  - CVE-2015-8812     A flaw was found in the iw_cxgb3 Infiniband driver.
    Whenever it could not send a packet because the network     was congested, it would free the packet buffer but later     attempt to send the packet again. This use-after-free     could result in a denial of service (crash or hang),     data loss or privilege escalation.

  - CVE-2015-8816     A use-after-free vulnerability was discovered in the USB     hub driver. This may be used by a physically present     user for privilege escalation.

  - CVE-2015-8830     Ben Hawkes of Google Project Zero reported that the AIO     interface permitted reading or writing 2 GiB of data or     more in a single chunk, which could lead to an integer     overflow when applied to certain filesystems, socket or     device types. The full security impact has not been     evaluated.

  - CVE-2016-0723     A use-after-free vulnerability was discovered in the     TIOCGETD ioctl. A local attacker could use this flaw for     denial-of-service.

  - CVE-2016-0774     It was found that the fix for CVE-2015-1805 in kernel     versions older than Linux 3.16 did not correctly handle     the case of a partially failed atomic read. A local,     unprivileged user could use this flaw to crash the     system or leak kernel memory to user space.

  - CVE-2016-2069     Andy Lutomirski discovered a race condition in flushing     of the TLB when switching tasks on an x86 system. On an     SMP system this could possibly lead to a crash,     information leak or privilege escalation.

  - CVE-2016-2384     Andrey Konovalov found that a crafted USB MIDI device     with an invalid USB descriptor could trigger a     double-free. This may be used by a physically present     user for privilege escalation.

  - CVE-2016-2543     Dmitry Vyukov found that the core sound sequencer driver     (snd-seq) lacked a necessary check for a NULL pointer,     allowing a user with access to a sound sequencer device     to cause a denial-of service (crash).

  - CVE-2016-2544, CVE-2016-2546, CVE-2016-2547,     CVE-2016-2548

    Dmitry Vyukov found various race conditions in the sound     subsystem (ALSA)'s management of timers. A user with     access to sound devices could use these to cause a     denial-of-service (crash or hang) or possibly for     privilege escalation.

  - CVE-2016-2545     Dmitry Vyukov found a flaw in list manipulation in the     sound subsystem (ALSA)'s management of timers. A user     with access to sound devices could use this to cause a     denial-of-service (crash or hang) or possibly for     privilege escalation.

  - CVE-2016-2549     Dmitry Vyukov found a potential deadlock in the sound     subsystem (ALSA)'s use of high resolution timers. A user     with access to sound devices could use this to cause a     denial-of-service (hang).

  - CVE-2016-2550     The original mitigation of CVE-2013-4312, limiting the     total number of files a user could queue on local     sockets, was flawed. A user given a local socket opened     by another user, for example through the systemd socket     activation mechanism, could make use of the other user's     quota, again leading to a denial-of-service (resource     exhaustion). This is fixed by accounting queued files to     the sender rather than the socket opener.
