Updated libtirpc packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
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.

These packages provide a transport-independent RPC (remote procedure call)

A flaw was found in the way libtirpc decoded RPC requests. A
specially-crafted RPC request could cause libtirpc to attempt to free a
buffer provided by an application using the library, even when the buffer
was not dynamically allocated. This could cause an application using
libtirpc, such as rpcbind, to crash. (CVE-2013-1950)

Red Hat would like to thank Michael Armstrong for reporting this issue.

Users of libtirpc should upgrade to these updated packages, which contain a
backported patch to correct this issue. All running applications using
libtirpc must be restarted for the update to take effect.
