Microsoft Internet Explorer "daxctle.ocx" KeyFrame Buffer Overflow Vulnerability

Quote:
A vulnerability has been identified in Microsoft Internet Explorer, which could be exploited by remote attackers to crash a vulnerable browser or take complete control of an affected system. This flaw is due to a memory corruption error when processing a specially crafted argument passed to the "KeyFrame()" method of a "DirectAnimation.PathControl" (daxctle.ocx) ActiveX object, which could be exploited by attackers to cause a denial of service or execute arbitrary commands by convincing a user to visit a malicious Web page.

FrSIRT confirmed this vulnerability on a fully patched Windows XP SP2 system. Exploit code is publicly available.
