3. Problem description:

FLAC is a Free Lossless Audio Codec. The flac package consists of a FLAC encoder and decoder in library form, a program to encode and decode FLAC files, a metadata editor for FLAC files and input plugins for various music players.

A security flaw was found in the way flac processed audio data. An attacker could create a carefully crafted FLAC audio file in such a way that it could cause an application linked with flac libraries to crash or execute arbitrary code when it was opened. (CVE-2007-4619)

Users of flac are advised to upgrade to this updated package, which contains a backported patch that resolves this issue.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188
