ZDI-10-012: Microsoft Internet Explorer Baseline Tag Rendering Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-10-012 January 21, 2010
The specific flaw exists due to the application rendering intertwined strike and center tags containing an element that manipulates the font baseline such as 'sub' or 'sup'. When this element pointer is removed the application will later dereference it even though it has been freed. Successful exploitation can lead to arbitrary code execution under the context of the currently logged in user.
