3. Description:

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

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.

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
