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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the ea_get function in fs/jfs/xattr.c in the Linux kernel through 4.17.1, a memory corruption bug in     JFS can be triggered by calling setxattr twice with two different extended attribute names on the same     file. This vulnerability can be triggered by an unprivileged user with the ability to create files and     execute programs. A kmalloc call is incorrect, leading to slab-out-of-bounds in jfs_xattr.
    (CVE-2018-12233)

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the linux package has been released.

  - CVE-2018-13406: An integer overflow in the     uvesafb_setcmap function could have result in local     attackers being able to crash the kernel or potentially     elevate privileges because kmalloc_array is not used     (bnc#1100418)

  - CVE-2018-13053: The alarm_timer_nsleep function had an     integer overflow via a large relative timeout because     ktime_add_safe was not used (bnc#1099924)

  - CVE-2018-9385: Prevent overread of the 'driver_override'     buffer (bsc#1100491)

  - CVE-2018-1118: Linux kernel vhost did not properly     initialize memory in messages passed between virtual     guests and the host operating system. This could have     allowed local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net     device file (bsc#1092472)

  - CVE-2018-12233: A memory corruption bug in JFS could     have been triggered by calling setxattr twice with two     different extended attribute names on the same file.

  - CVE-2018-8781: The udl_fb_mmap function had an     integer-overflow vulnerability allowing local users with     access to the udldrmfb driver to obtain full read and     write permissions on kernel physical pages, resulting in     a code execution in kernel space (bsc#1090643)

  - CVE-2018-10124: The kill_something_info function in     kernel/signal.c might have allowed local users to cause     a denial of service via an INT_MIN argument     (bnc#1089752)

  - CVE-2018-10087: The kernel_wait4 function in     kernel/exit.c might have allowed local users to cause a     denial of service by triggering an attempted use of the
