Ubuntu 12.04 LTS : linux-lts-trusty vulnerabilities (USN-2749-1)

Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Benjamin Randazzo discovered an information leak in the md (multiple
device) driver when the bitmap_info.file is disabled. A local
privileged attacker could use this to obtain sensitive information
from the kernel. (CVE-2015-5697)

Marc-Andre Lureau discovered that the vhost driver did not properly
release the userspace provided log file descriptor. A privileged
attacker could use this to cause a denial of service (resource
exhaustion). (CVE-2015-6252).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected linux-image-3.13-generic and / or
linux-image-3.13-generic-lpae packages.
