The Red Hat Security Response Team has rated this update as having
Important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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

* A race condition flaw, leading to heap-based buffer overflows, was
found in the way the Linux kernel's N_TTY line discipline (LDISC)
implementation handled concurrent processing of echo output and TTY
write operations originating from user space when the underlying TTY
driver was PTY. An unprivileged, local user could use this flaw to
crash the system or, potentially, escalate their privileges on the
system. (CVE-2014-0196, Important)

All kernel users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The system
