This signature detects attempts to exploit a known vulnerability in Windows Media Encoder 9. An attacker can create a malicious Web site with Web pages containing dangerous ActiveX calls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.
The Microsoft Windows Media Encoder 9 ActiveX control is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. An attacker can exploit this issue to execute arbitrary code in the context of an application using the affected ActiveX control (typically Internet Explorer). Failed attacks will likely cause denial-of-service conditions.
