Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


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-3.11.0-18-generic and / or
linux-image-3.11.0-18-generic-lpae packages.

Risk factor :

Medium / CVSS Base Score : 4.4
