RHEL 6 : libtirpc (RHSA-2013:0884)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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) 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.
