-- 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

the use of a pointer after it has been freed. Successful exploitation
can lead to remote system compromise under the credentials of the
currently logged in user.
