Solution
Please Install the Updated Packages.
Insight
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.
Affected
libtirpc on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)
