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.
The specific flaw exists within the copy constructor for a specific DOM object. When duplicated, more than one reference can be made of anything assigned to it's properties. When the variable/object goes out of scope, these properties will be deallocated twice. This results in a heap corruption which can lead to code execution under the context of the current user.
Microsoft has issued an update to correct this vulnerability. More details can be found at:
