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 keeps track of in-memory objects representing rows in an HTML table. By manipulating a document's elements an attacker can force a CTableRow object in memory to be reused after it has been freed. An attacker can leverage this vulnerability to execute code under the context of the current process.
