Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

A bug was discovered in the XFS filesystem's handling of pathnames. A
local attacker could exploit this to crash the system, leading to a
denial of service, or gain root privileges. (CVE-2011-4077)

Nick Bowler discovered the kernel GHASH message digest algorithm
incorrectly handled error conditions. A local attacker could exploit
this to cause a kernel oops. (CVE-2011-4081)

A flaw was found in the Journaling Block Device (JBD). A local
attacker able to mount ext3 or ext4 file systems could exploit this to
crash the system, leading to a denial of service. (CVE-2011-4132)

Clement Lecigne discovered a bug in the HFS file system bounds
checking. When a malformed HFS file system is mounted a local user
could crash the system or gain root privileges. (CVE-2011-4330).

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 packages.
