Zero Day Initiative Advisory 12-093 - 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 specific flaw exists within the way Internet Explorer handles dynamically changed colspans on a column in a table with the table-layout:fixed style. If the colspan is increased after initial creation it will result in a heap overflow. This can lead to remote code execution under the context of the current program.
