-- Vulnerability Details:
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 web page.
The specific flaw exists during deallocation of a circular dereference
for a CAttrArray object. If the CAttrArray object has been freed prior
to the tearing down of the webpage, the application will access the
freed memory during the deallocation of the circular dereference. This
can lead to code execution under the context of the currently logged in
user.

Microsoft has issued an update to correct this vulnerability. More
