Red Hat Security Advisory 2013-1173-01 - 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 Stream Control Transmission Protocol implementation handled duplicate cookies. If a local user queried SCTP connection information at the same time a remote attacker has initialized a crafted SCTP connection to the system, it could trigger a NULL pointer dereference, causing the system to crash.

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 Stream Control
Transmission Protocol (SCTP) implementation handled duplicate cookies. If a
local user queried SCTP connection information at the same time a remote
attacker has initialized a crafted SCTP connection to the system, it could
trigger a NULL pointer dereference, causing the system to crash.
(CVE-2013-2206, Important)

* It was found that the fix for CVE-2012-3552 released via RHSA-2012:1304
introduced an invalid free flaw in the Linux kernel's TCP/IP protocol suite
implementation. A local, unprivileged user could use this flaw to corrupt
kernel memory via crafted sendmsg() calls, allowing them to cause a denial
of service or, potentially, escalate their privileges on the system.
(CVE-2013-2224, Important)

* A flaw was found in the Linux kernel's Performance Events implementation.
On systems with certain Intel processors, a local, unprivileged user could
use this flaw to cause a denial of service by leveraging the perf subsystem
to write into the reserved bits of the OFFCORE_RSP_0 and OFFCORE_RSP_1
model-specific registers. (CVE-2013-2146, Moderate)

* An invalid pointer dereference flaw was found in the Linux kernel's
TCP/IP protocol suite implementation. A local, unprivileged user could use
this flaw to crash the system or, potentially, escalate their privileges on
the system by using sendmsg() with an IPv6 socket connected to an IPv4
destination. (CVE-2013-2232, Moderate)

* Information leak flaws in the Linux kernel's Bluetooth implementation
could allow a local, unprivileged user to leak kernel memory to user-space.
(CVE-2012-6544, Low)

* An information leak flaw in the Linux kernel could allow a privileged,
local user to leak kernel memory to user-space. (CVE-2013-2237, Low)

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.

Users should 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 (http://bugzilla.redhat.com/):

922414 - CVE-2012-6544 Kernel: Bluetooth: HCI & L2CAP information leaks
971309 - CVE-2013-2146 Kernel: perf/x86: offcore_rsp valid mask for SNB/IVB
976562 - CVE-2013-2206 kernel: sctp: duplicate cookie handling NULL pointer dereference
979936 - CVE-2013-2224 kernel: net: IP_REPOPTS invalid free
981220 - CVE-2013-2237 Kernel: net: af_key: initialize satype in key_notify_policy_flush
981552 - CVE-2013-2232 Kernel: ipv6: using ipv4 vs ipv6 structure during routing lookup in sendmsg
