Description

Mozilla upgraded several third party libraries used in media rendering to address multiple memory safety and stability bugs identified by members of the Mozilla community. Some of the bugs discovered could potentially be used by an attacker to crash a victim's browser and execute arbitrary code on their computer. liboggz, libvorbis, and liboggplay were all upgraded to address these issues.

Audio and video capabilities were added in Firefox 3.5 so prior releases of Firefox were not affected.

The original version of this advisory incorrectly included bug 500254 as part of CVE-2009-3370. That bug was actually fixed in Firefox 3.5.2 as CVE-2009-2663
