Red Hat Security Advisory
Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2013:1166-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1166.html
Issue date: 2013-08-20
CVE Names: CVE-2013-2147 CVE-2013-2164 CVE-2013-2206
CVE-2013-2224 CVE-2013-2232 CVE-2013-2234
CVE-2013-2237
=====================================================================
1. Summary:
Updated kernel packages that fix multiple security issues and several bugs
are now available for Red Hat Enterprise Linux 5.
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64
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-2012:1540
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)
* 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 could allow a privileged,
local user to leak kernel memory to user-space. (CVE-2013-2164,
CVE-2013-2147, CVE-2013-2234, 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/):
971242 - CVE-2013-2147 Kernel: cpqarray/cciss: information leak via ioctl
973100 - CVE-2013-2164 Kernel: information leak in cdrom driver
976562 - CVE-2013-2206 kernel: sctp: duplicate cookie handling NULL pointer dereference
979936 - CVE-2013-2224 kernel: net: IP_REPOPTS invalid free
980995 - CVE-2013-2234 Kernel: net: information leak in AF_KEY notify
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
