Ubuntu 12.04 LTS : linux-lts-raring vulnerabilities (USN-2158-1)

medium Nessus Plugin ID 73288

Language:

Synopsis

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

Description

Stephan Mueller reported an error in the Linux kernel's ansi cprng random number generator. This flaw makes it easier for a local attacker to break cryptographic protections. (CVE-2013-4345)

Nico Golde and Fabian Yamaguchi reported buffer underflow errors in the implementation of the XFS filesystem in the Linux kernel. A local user with CAP_SYS_ADMIN could exploit these flaw to cause a denial of service (memory corruption) or possibly other unspecified issues.
(CVE-2013-6382)

An information leak was discovered in the Linux kernel when built with the NetFilter Connection Tracking (NF_CONNTRACK) support for IRC protocol (NF_NAT_IRC). A remote attacker could exploit this flaw to obtain potentially sensitive kernel information when communicating over a client- to-client IRC connection(/dcc) via a NAT-ed network.
(CVE-2014-1690).

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-3.8-generic package.
