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):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.(CVE-2020-0466)In the l2tp     subsystem, there is a possible use after free due to a     race condition. This could lead to local escalation of     privilege with System execution privileges     needed.(CVE-2020-27067)In the nl80211_policy policy of     nl80211.c, there is a possible out of bounds read due     to a missing bounds check. This could lead to local     information disclosure with System execution privileges     needed.(CVE-2020-27068)In audit_free_lsm_field of     auditfilter.c, there is a possible bad kfree due to a     logic error in audit_data_to_entry. This could lead to     local escalation of privilege with no additional     execution privileges needed.(CVE-2020-0444)In various     methods of hid-multitouch.c, there is a possible out of     bounds write due to a missing bounds check. This could     lead to local escalation of privilege with no     additional execution privileges     needed.(CVE-2020-0465)Use-after-free vulnerability in     fs/block_dev.c in the Linux kernel before 5.8 allows     local users to gain privileges or cause a denial of     service by leveraging improper access to a certain     error field.(CVE-2020-15436)The Linux kernel before     version 5.8 is vulnerable to a NULL pointer dereference     in     drivers/tty/serial/8250/8250_core.c:serial8250_isa_init
    _ports() that allows local users to cause a denial of     service by using the p->serial_in pointer which     uninitialized.(CVE-2020-15437)A flaw was found in the     Linux kernels implementation of MIDI, where an attacker     with a local account and the permissions to issue an     ioctl commands to midi devices, could trigger a     use-after-free. A write to this specific memory while     freed and before use could cause the flow of execution     to change and possibly allow for memory corruption or     privilege escalation.(CVE-2020-27786)Array index out of     bounds access when setting extended attributes on     journaling filesystems.(CVE-2020-27815)NULL-ptr deref     in the spk_ttyio_receive_buf2() function in     spk_ttyio.c(CVE-2020-27830)An issue was discovered in
    __split_huge_pmd in mm/huge_memory.c in the Linux     kernel before 5.7.5. The copy-on-write implementation     can grant unintended write access because of a race     condition in a THP mapcount check, aka     CID-c444eb564fb1.(CVE-2020-29368)An issue was     discovered in kmem_cache_alloc_bulk in mm/slub.c in the     Linux kernel before 5.5.11. The slowpath lacks the     required TID increment, aka     CID-fd4d9c7d0c71.(CVE-2020-29370)An issue was     discovered in romfs_dev_read in fs/romfs/storage.c in     the Linux kernel before 5.8.4. Uninitialized memory     leaks to userspace, aka     CID-bcf85fcedfdd.(CVE-2020-29371)A locking     inconsistency issue was discovered in the tty subsystem     of the Linux kernel through 5.9.13.
    drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may     allow a read-after-free attack against TIOCGSID, aka     CID-c8bcd9c5be24.(CVE-2020-29660)A locking issue was     discovered in the tty subsystem of the Linux kernel     through 5.9.13. drivers/tty/tty_jobctrl.c allows a     use-after-free attack against TIOCSPGRP, aka     CID-54ffccbf053b.(CVE-2020-29661)A slab-out-of-bounds     read in fbcon in the Linux kernel before 5.9.7 could be     used by local attackers to read privileged information     or potentially crash the kernel, aka CID-3c4e0dff2095.
    This occurs because KD_FONT_OP_COPY in     drivers/tty/vt/vt.c can be used for manipulations such     as font height.(CVE-2020-28974) An issue was discovered     in the Linux kernel through 5.9.1, as used with Xen     through 4.14.x. Guest OS users can cause a denial of     service (host OS hang) via a high rate of events to     dom0, aka CID-e99502f76271.(CVE-2020-27673)An issue was     discovered in drivers/accessibility/speakup/spk_ttyio.c     in the Linux kernel through 5.9.9. Local attackers on     systems with the speakup driver could cause a local     denial of service attack, aka CID-d41227544427. This     occurs because of an invalid free when the line     discipline is used more than once.(CVE-2020-28941)An     issue was discovered in the Linux kernel through 5.9.1,     as used with Xen through 4.14.x.
    drivers/xen/events/events_base.c allows event-channel     removal during the event-handling loop (a race     condition). This can cause a use-after-free or NULL     pointer dereference, as demonstrated by a dom0 crash     via events for an in-reconfiguration paravirtualized     device, aka CID-073d0552ead5.(CVE-2020-27675)A buffer     over-read (at the framebuffer layer) in the fbcon code     in the Linux kernel before 5.8.15 could be used by     local attackers to read kernel memory, aka     CID-6735b4632def.(CVE-2020-28915)A flaw was found in     the Linux kernel. A use-after-free memory flaw was     found in the perf subsystem allowing a local attacker     with permission to monitor perf events to corrupt     memory and possibly escalate privileges. The highest     threat from this vulnerability is to data     confidentiality and integrity as well as system     availability.(CVE-2020-14351)A flaw in the way reply     ICMP packets are limited in the Linux kernel     functionality was found that allows to quickly scan     open UDP ports. This flaw allows an off-path remote     user to effectively bypassing source port UDP     randomization. The highest threat from this     vulnerability is to confidentiality and possibly     integrity, because software that relies on UDP source     port randomization are indirectly affected as well.
    Kernel versions before 5.10 may be vulnerable to this     issue.(CVE-2020-25705)race condition in fg_console can     lead to use-after-free in     con_font_op.(CVE-2020-25668)use-after-free read in     sunkbd_reinit in     drivers/input/keyboard/sunkbd.c.(CVE-2020-25669)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)

  - 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: AndroidVersions: Android kernelAndroid ID:
    A-147802478References: Upstream kernel (CVE-2020-0466)

  - An issue was discovered in ioapic_lazy_update_eoi in arch/x86/kvm/ioapic.c in the Linux kernel before     5.9.2. It has an infinite loop related to improper interaction between a resampler and edge triggering,     aka CID-77377064c3a9. (CVE-2020-27152)

  - In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking     in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal     in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker     has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are     proxied via an attacker-selected backstore. (CVE-2020-28374)

  - An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.
    (CVE-2021-3347)

  - A local privilege escalation was discovered in the Linux kernel before 5.10.13. Multiple race conditions     in the AF_VSOCK implementation are caused by wrong locking in net/vmw_vsock/af_vsock.c. The race     conditions were implicitly introduced in the commits that added VSOCK multi-transport support.
    (CVE-2021-26708)

  - 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. 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 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)

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

The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes.

The version of AOS installed on the remote host is prior to 5.20.4. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.4 advisory.

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw     V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists. (CVE-2022-23307)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

  - It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-     default configurations. This could allows attackers with control over Thread Context Map (MDC) input data     when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for     example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input     data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some     environments and local code execution in all environments.

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:

    A-147802478References: Upstream kernel(CVE-2020-0466)In     fs/ocfs2/cluster/ nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216)In the Linux kernel     before 5.2, a setxattr operation, after a mount of a     crafted ext4 image, can cause a slab-out-of-bounds     write access because of an ext4_xattr_set_entry     use-after-free in fs/ext4/xattr.c when a large old_size     value is used in a memset call, aka     CID-345c0dbf3a30.(CVE-2019-19319)In the Linux kernel     before version 4.12, Kerberos 5 tickets decoded when     using the RXRPC keys incorrectly assumes the size of a     field. 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)
