Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Sasha Levin reported a flaw in the Linux kernel's point-to-point
protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP).
A local user could exploit this flaw to gain administrative
privileges. (CVE-2014-4943)

An flaw was discovered in the Linux kernel's audit subsystem when
auditing certain syscalls. A local attacker could exploit this flaw to
obtain potentially sensitive single-bit values from kernel memory or
cause a denial of service (OOPS). (CVE-2014-3917)

Don Bailey discovered a flaw in the LZO decompress algorithm used by
the Linux kernel. An attacker could exploit this flaw to cause a
denial of service (memory corruption or OOPS). (CVE-2014-4608).

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.
