Description


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
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.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* A buffer overflow flaw was found in the way the qeth_snmp_command()
function in the Linux kernel's QETH network device driver implementation
handled SNMP IOCTL requests with an out-of-bounds length. A local,
unprivileged user could use this flaw to crash the system or, potentially,
escalate their privileges on the system. (CVE-2013-6381, Important)

* A flaw was found in the way the get_dumpable() function return value was
interpreted in the ptrace subsystem of the Linux kernel. When
'fs.suid_dumpable' was set to 2, a local, unprivileged local user could
use this flaw to bypass intended ptrace restrictions and obtain
potentially sensitive information. (CVE-2013-2929, Low)

* It was found that certain protocol handlers in the Linux kernel's
networking implementation could set the addr_len value without initializing
the associated data structure. A local, unprivileged user could use this
flaw to leak kernel stack memory to user space using the recvmsg, recvfrom,
and recvmmsg system calls (CVE-2013-7263, CVE-2013-7265, 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.

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.

Am I vulnerable?

The constraints below list the versions that this vulnerability is patched in, and versions that are unaffected. If a patch is ready but unrealeased, then it is pending.

Or, you can just let us figure it out for you! Appcanary continously monitor your installed packages, and tell you if any of them are vulnerable.
