3. Description:

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.

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
https://access.redhat.com/kb/docs/DOC-11259
