Description

This vulnerability could allow 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 specific flaw exists within the handling of CDataBindTask objects. By manipulating a document's elements, an attacker can force a dangling pointer to be reused after it has been freed. An attacker could leverage this vulnerability to execute code under the context of the current process.
