=====================================================================
1. Summary:
Updated kernel packages that fix multiple security issues, address several
hundred bugs, and add numerous enhancements are now available as part of
the ongoing support and maintenance of Red Hat Enterprise Linux version 6.
This is the fifth regular update.
The Red Hat Security Response Team has rated this update as having
important 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.

3. Description:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* A flaw was found in the way the Linux kernel's IPv6 implementation
handled certain UDP packets when the UDP Fragmentation Offload (UFO)
feature was enabled. A remote attacker could use this flaw to crash the
system or, potentially, escalate their privileges on the system.
(CVE-2013-4387, Important)
* A flaw was found in the way the Linux kernel handled the creation of
temporary IPv6 addresses. If the IPv6 privacy extension was enabled
(/proc/sys/net/ipv6/conf/eth0/use_tempaddr set to '2'), an attacker on
the
local network could disable IPv6 temporary address generation, leading to a
potential information disclosure. (CVE-2013-0343, Moderate)
* A flaw was found in the way the Linux kernel handled HID (Human Interface
Device) reports with an out-of-bounds Report ID. An attacker with physical
access to the system could use this flaw to crash the system or,
potentially, escalate their privileges on the system. (CVE-2013-2888,
Moderate)
* An off-by-one flaw was found in the way the ANSI CPRNG implementation in
the Linux kernel processed non-block size aligned requests. This could lead
to random numbers being generated with less bits of entropy than expected
when ANSI CPRNG was used. (CVE-2013-4345, Moderate)
* It was found that the fix for CVE-2012-2375 released via RHSA-2012:1580
accidentally removed a check for small-sized result buffers. A local,
unprivileged user with access to an NFSv4 mount with ACL support could use
this flaw to crash the system or, potentially, escalate their privileges on
the system . (CVE-2013-4591, Moderate)
* A flaw was found in the way IOMMU memory mappings were handled when
moving memory slots. A malicious user on a KVM host who has the ability to
assign a device to a guest could use this flaw to crash the host.
(CVE-2013-4592, Moderate)
* Heap-based buffer overflow flaws were found in the way the Zeroplus and
Pantherlord/GreenAsia game controllers handled HID reports. An attacker
with physical access to the system could use these flaws to crash the
system or, potentially, escalate their privileges on the system.
(CVE-2013-2889, CVE-2013-2892, Moderate)
* Two information leak flaws were found in the logical link control (LLC)
implementation in the Linux kernel. A local, unprivileged user could use
these flaws to leak kernel stack memory to user space. (CVE-2012-6542,
CVE-2013-3231, Low)
* A heap-based buffer overflow in the way the tg3 Ethernet driver parsed
the vital product data (VPD) of devices could allow an attacker with
physical access to a system to cause a denial of service or, potentially,
escalate their privileges. (CVE-2013-1929, Low)
* Information leak flaws in the Linux kernel could allow a privileged,
local user to leak kernel memory to user space. (CVE-2012-6545,
CVE-2013-1928, CVE-2013-2164, CVE-2013-2234, Low)
* A format string flaw was found in the Linux kernel's block layer.
A privileged, local user could potentially use this flaw to escalate their
privileges to kernel level (ring0). (CVE-2013-2851, Low)
Red Hat would like to thank Stephan Mueller for reporting CVE-2013-4345,
and Kees Cook for reporting CVE-2013-2851.
This update also fixes several hundred bugs and adds enhancements. Refer to
the Red Hat Enterprise Linux 6.5 Release Notes for information on the most
significant of these changes, and the Technical Notes for further
information, both linked to in the References.
All Red Hat Enterprise Linux 6 users are advised to install these updated
packages, which correct these issues, and fix the bugs and add the
enhancements noted in the Red Hat Enterprise Linux 6.5 Release Notes and
Technical Notes. 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/knowledge/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.
