Updated kernel packages that fix multiple 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.
The kernel packages contain the Linux kernel, the core of any Linux
This update fixes the following security issues:
* A flaw was found in the tcp_read_sock() function in the Linux kernel's
IPv4 TCP/IP protocol suite implementation in the way socket buffers (skb)
were handled. A local, unprivileged user could trigger this issue via a
call to splice(), leading to a denial of service. (CVE-2013-2128,
* Information leak flaws in the Linux kernel could allow a local,
unprivileged user to leak kernel memory to user-space. (CVE-2012-6548,
CVE-2013-2634, CVE-2013-2635, CVE-2013-3222, CVE-2013-3224, CVE-2013-3225,
* An information leak was found in the Linux kernel's POSIX signals
implementation. A local, unprivileged user could use this flaw to bypass
the Address Space Layout Randomization (ASLR) security feature.
* A format string flaw was found in the ext3_msg() function in the Linux
kernel's ext3 file system implementation. A local user who is able to mount
an ext3 file system could use this flaw to cause a denial of service or,
potentially, escalate their privileges. (CVE-2013-1848, Low)
* A format string flaw was found in the b43_do_request_fw() function in the
Linux kernel's b43 driver implementation. A local user who is able to
specify the "fwpostfix" b43 module parameter could use this flaw to cause a
denial of service or, potentially, escalate their privileges.
* A NULL pointer dereference flaw was found in the Linux kernel's ftrace
and function tracer implementations. A local user who has the CAP_SYS_ADMIN
capability could use this flaw to cause a denial of service.
Red Hat would like to thank Kees Cook for reporting CVE-2013-2852.
This update also fixes several bugs. Documentation for these changes will
be available shortly from the Technical Notes document linked to in the
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.
