Who is Vulnerable?
Vulnerability Description	MPEG Layer-3 audio codecs are the MPEG Layer-3 Audio Codec for Microsoft DirectShow (l3codecx.ax) and the Fraunhofer IIS MPEG Layer-3 ACM codecs (L3codeca.acm and L3codecp.acm). These MPEG Layer-3 audio codecs are provided along with Windows Media files on affected versions of Microsoft Windows. A stack overflow vulnerability has been reported in the way that Microsoft MPEG Layer-3 codecs handle AVI media files. The vulnerability is due to an error in Microsoft MPEG Layer-3 audio codecs that fail to properly handle specially crafted AVI files containing an MPEG Layer-3 audio stream. A remote attacker could trigger this flaw by convincing the victim to open a specially crafted AVI file. Successful exploitation of this issue may allow execution of arbitrary code once the malformed file is opened on a vulnerable system.
