"Updated libsndfile 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.

The libsndfile packages provide a library for reading and writing
sound files.

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way the libsndfile library processed certain Ensoniq
PARIS Audio Format (PAF) audio files. An attacker could create a
specially crafted PAF file that, when opened, could cause an
application using libsndfile to crash or, potentially, execute
arbitrary code with the privileges of the user running the
application. (CVE-2011-2696)

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