The CentOS Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS6:CLSA-2026:1782150058 advisory.

  - A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in     ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a     file in a crafted ext4 filesystem image. (CVE-2018-10879)

  - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout()     and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)

  - In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is     used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the     rds_rdma_extra_size function in net/rds/rdma.c). (CVE-2018-5332)

  - In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead     to local escalation of privilege with no additional execution privileges needed. User interaction is not     needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-113509306. References:
    Upstream kernel. (CVE-2018-9568)

  - An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c     in the Linux kernel through 5.1.5. It allows local users to cause a denial of service or possibly have     unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a     double fetch vulnerability. NOTE: a third party reports that this is unexploitable because the doubly     fetched value is not used (CVE-2019-12456)

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

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3753-2 advisory.

    It was discovered that the generic SCSI driver in the Linux kernel did not properly enforce permissions on     kernel memory access. A local attacker could use this to expose sensitive information or possibly elevate     privileges. (CVE-2017-13168)

    Wen Xu discovered that a use-after-free vulnerability existed in the ext4 filesystem implementation in the     Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10876,     CVE-2018-10879)

    Wen Xu discovered that a buffer overflow existed in the ext4 filesystem implementation in the Linux     kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10877)

    Wen Xu discovered that an out-of-bounds write vulnerability existed in the ext4 filesystem implementation     in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted,     could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10878,     CVE-2018-10882)

    Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly keep meta-     data information consistent in some situations. An attacker could use this to construct a malicious ext4     image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10881)

    Shankara Pailoor discovered that the JFS filesystem implementation in the Linux kernel contained a buffer     overflow when handling extended attributes. A local attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2018-12233)

    Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly handle an     error condition with a corrupted xfs image. An attacker could use this to construct a malicious xfs image     that, when mounted, could cause a denial of service (system crash). (CVE-2018-13094)

    It was discovered that the Linux kernel did not properly handle setgid file creation when performed by a     non-member of the group. A local attacker could use this to gain elevated privileges. (CVE-2018-13405)

    Silvio Cesare discovered that the generic VESA frame buffer driver in the Linux kernel contained an     integer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2018-13406)

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 installation on the remote host is affected by the following vulnerabilities :

  - A division-by-zero in set_termios(), when debugging is     enabled, was found in the Linux kernel. When the     [io_ti] driver is loaded, a local unprivileged attacker     can request incorrect high transfer speed in the     change_port_settings() in the     drivers/usb/serial/io_ti.c so that the divisor value     becomes zero and causes a system crash resulting in a     denial of service. (CVE-2017-18360)

  - Since Linux kernel version 3.2, the mremap() syscall     performs TLB flushes after dropping pagetable locks. If     a syscall such as ftruncate() removes entries from the     pagetables of a task that is in the middle of mremap(),     a stale TLB entry can remain for a short time that     permits access to a physical page after it has been     released back to the page allocator and     reused.(CVE-2018-18281)

  - A flaw was discovered in the Linux kernel's USB     subsystem in the __usb_get_extra_descriptor() function     in the drivers/usb/core/usb.c which mishandles a size     check during the reading of an extra descriptor data.
    By using a specially crafted USB device which sends a     forged extra descriptor, an unprivileged user with     physical access to the system can potentially cause a     privilege escalation or trigger a system crash or lock     up and thus to cause a denial of service     (DoS).(CVE-2018-20169)

  - It was found that the Linux kernel can hit a BUG_ON()     statement in the __xfs_get_blocks() in the     fs/xfs/xfs_aops.c because of a race condition between     direct and memory-mapped I/O associated with a hole in     a file that is handled with BUG_ON() instead of an I/O     failure. This allows a local unprivileged attacker to     cause a system crash and a denial of     service.(CVE-2016-10741)

  - A use-after-free flaw can occur in the Linux kernel due     to a race condition between packet_do_bind() and     packet_notifier() functions called for an AF_PACKET     socket. An unprivileged, local user could use this flaw     to induce kernel memory corruption on the system,     leading to an unresponsive system or to a crash. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out. (CVE-2018-18559)

  - An issue was discovered in can_can_gw_rcv in     net/can/gw.c in the Linux kernel through 4.19.13. The     CAN frame modification rules allow bitwise logical     operations that can be also applied to the can_dlc     field. Because of a missing check, the CAN drivers may     write arbitrary content beyond the data registers in     the CAN controller's I/O memory when processing can-gw     manipulated outgoing frames. This is related to     cgw_csum_xor_rel. An unprivileged user can trigger a     system crash (general protection fault).(CVE-2019-3701)

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause a use-after-free in     ext4_xattr_set_entry function and a denial of service     or unspecified other impact may occur by renaming a     file in a crafted ext4 filesystem     image.(CVE-2018-10879)

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound write in     jbd2_journal_dirty_metadata(), a denial of service, and     a system crash by mounting and operating on a crafted     ext4 filesystem image.(CVE-2018-10883)

  - 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)

  - The Linux kernel is vulnerable to a NULL pointer     dereference in the ext4/xattr.c:ext4_xattr_inode_hash()     function. An attacker could trick a legitimate user or     a privileged attacker could exploit this to cause a     NULL pointer dereference with a crafted ext4 image.

The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-3620: Local attackers on baremetal systems     could use speculative code patterns on hyperthreaded     processors to read data present in the L1 Datacache used     by other hyperthreads on the same CPU core, potentially     leaking sensitive data. (bnc#1087081).

  - CVE-2018-3646: Local attackers in virtualized guest     systems could use speculative code patterns on     hyperthreaded processors to read data present in the L1     Datacache used by other hyperthreads on the same CPU     core, potentially leaking sensitive data, even from     other virtual machines or the host system.
    (bnc#1089343).

  - CVE-2018-5391 aka 'FragmentSmack': A flaw in the IP     packet reassembly could be used by remote attackers to     consume lots of CPU time (bnc#1103097).

  - CVE-2018-10876: A flaw was found 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. (bnc#1099811)

  - CVE-2018-10877: The 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.
    (bnc#1099846)

  - CVE-2018-10878: A flaw was found in the ext4 filesystem.
    A local user can cause an out-of-bounds write and a     denial of service or unspecified other impact is     possible by mounting and operating a crafted ext4     filesystem image. (bnc#1099813)

  - CVE-2018-10879: A flaw was found in the ext4 filesystem.
    A local user can cause a use-after-free in     ext4_xattr_set_entry function and a denial of service or     unspecified other impact may occur by renaming a file in     a crafted ext4 filesystem image. (bnc#1099844)

  - CVE-2018-10880: 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.
    (bnc#1099845)

  - CVE-2018-10881: A flaw was found in the ext4 filesystem.
    A local user can cause an out-of-bound access in     ext4_get_group_info function, a denial of service, and a     system crash by mounting and operating on a crafted ext4     filesystem image. (bnc#1099864)

  - CVE-2018-10882: A flaw was found in the 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. (bnc#1099849)

  - CVE-2018-10883: A flaw was found in the ext4 filesystem.
    A local user can cause an out-of-bounds write in     jbd2_journal_dirty_metadata(), a denial of service, and     a system crash by mounting and operating on a crafted     ext4 filesystem image. (bnc#1099863)

The update package also includes non-security fixes. See advisory for details.
