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

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

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.

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.

Solution :

Update the affected linux-image-3.8.0-38-generic package.

Risk factor :

Medium / CVSS Base Score : 5.8
CVSS Temporal Score : 5.0
Public Exploit Available : false
