Red Hat Security Advisory 2013-1436-01
Posted Oct 17, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-1436-01 - 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. 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.

Synopsis:          Moderate: kernel security and bug fix update
Advisory ID:       RHSA-2013:1436-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-1436.html
Issue date:        2013-10-16
CVE Names:         CVE-2013-4162 CVE-2013-4299 
=====================================================================

1. Summary:

Updated kernel packages that fix two security issues and several bugs are
now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258

To install kernel packages manually, use "rpm -ivh [package]". Do not use
"rpm -Uvh" as that will remove the running kernel binaries from your
system. You may use "rpm -e" to remove old kernels after determining that
the new kernel functions properly on your system.

5. Bugs fixed (https://bugzilla.redhat.com/):

987627 - CVE-2013-4162 Kernel: net: panic while pushing pending data out of a IPv6 socket with UDP_CORK enabled
1004233 - CVE-2013-4299 kernel: dm: dm-snapshot data leak
