medium Nessus Plugin ID 72900

Language:

Synopsis

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

Description

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)

Matthew Thode reported a denial of service vulnerability in the Linux kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN capability (and the SELinux mac_admin permission if running in enforcing mode) could exploit this flaw to cause a denial of service (kernel crash). (CVE-2014-1874)

An information leak was discovered in the Linux kernel's NFS filesystem. A local users with write access to an NFS share could exploit this flaw to obtain potential sensative information from kernel memory. (CVE-2014-2038).

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-3.11-generic and / or linux-image-3.11-generic-lpae packages.
