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

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
(CVSS2#AV:L/AC:M/Au:S/C:N/I:N/A:C)
CVSS Temporal Score : 3.8
