[USN-2158-1] Linux kernel (Raring HWE) vulnerabilities

Severity Medium

CVEs 3

Several security issues were fixed in the kernel.

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)
