Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3127-1)

high Nessus Plugin ID 94731

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3127-1 advisory.

 - The snd_compress_check_input function in sound/core/compress_offload.c in the ALSA subsystem in the Linux kernel before 3.17 does not properly check for an integer overflow, which allows local users to cause a denial of service (insufficient memory allocation) or possibly have unspecified other impact via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl call. (CVE-2014-9904)

 - mm/memory.c in the Linux kernel before 4.1.4 mishandles anonymous pages, which allows local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero. (CVE-2015-3288)

 - Xen and the Linux kernel through 4.5.x do not properly suppress hugetlbfs support in x86 PV guests, which allows local PV guest OS users to cause a denial of service (guest OS crash) by attempting to access a hugetlbfs mapped area. (CVE-2016-3961)

 - The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allows local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file. (CVE-2016-7042)

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

Solution

Update the affected kernel package.
