Ubuntu 10.04 LTS : linux-ec2 vulnerabilities (USN-1299-1)

High Nessus Plugin ID 57300

Synopsis

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

Description

Peter Huewe discovered an information leak in the handling of reading
security-related TPM data. A local, unprivileged user could read the
results of a previous TPM command. (CVE-2011-1162)

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)

A bug was found in the way headroom check was performed in
udp6_ufo_fragment() function. A remote attacker could use this flaw to
crash the system. (CVE-2011-4326)

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 linux-image-2.6-ec2 package.
