  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.");
