This vulnerability allows remote 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 or open a malicious file.

The vulnerability relates to how Internet Explorer processes style attributes. By manipulating a document's elements an attacker can force an array allocated by a CStyleAttrArray object to be processed as if it were a CAttrArray object. An attacker can leverage this vulnerability to execute code under the context of the current process.
