Ubuntu 14.04 LTS : linux vulnerability (USN-2999-1)

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


Synopsis :

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

Description :

Jann Horn discovered that eCryptfs improperly attempted to use the
mmap() handler of a lower filesystem that did not implement one,
causing a recursive page fault to occur. A local unprivileged attacker
could use to cause a denial of service (system crash) or possibly
execute arbitrary code with administrative privileges.

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,
linux-image-3.13-generic-lpae and / or linux-image-3.13-lowlatency
packages.

Risk factor :

CVSS Temporal Score : 6.8
