Test ID:1.3.6.1.4.1.25623.1.0.871053
Category:Red Hat Local Security Checks
Title:RedHat Update for kernel RHSA-2013:1436-01
Summary:The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* A flaw was found in the way the Linux kernel's TCP/IP protocol suite
implementation handled IPv6 sockets that used the UDP_CORK option. A local,
unprivileged user could use this flaw to cause a denial of
service. (CVE-2013-4162, Moderate)

* An information leak flaw was found in the way Linux kernel's device
mapper subsystem, under certain conditions, interpreted data written to
snapshot block devices. An attacker could use this flaw to read data from
disk blocks in free space, which are normally inaccessible. (CVE-2013-4299,
Moderate)

Red Hat would like to thank Hannes Frederic Sowa for reporting
CVE-2013-4162 and Fujitsu for reporting CVE-2013-4299.

This update also fixes several bugs. Documentation for these changes will
be available shortly from the Technical Notes document linked to in the
References section.

All kernel users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The system must be
rebooted for this update to take effect.

Affected Software/OS:
kernel on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
