Vulnerability Details

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.

The specific flaw exists in the DirectAnimation.DATuple ActiveX control when improperly calling the Nth() method. By supplying a positive integer we can control a data reference calculation that is later used to control execution. The problem is due to the lack of sanity checking on the index used during a call to TupleNthBvrImpl::GetTypeInfo() in danim.dll.

Vendor Response

Microsoft has issued an update to correct this vulnerability. More details can be found at:
