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 vulnerability relates to how Internet Explorer keeps track of table rows when performing layout of HTML tables. By manipulating a document's elements, an attacker can cause Internet Explorer to read beyond the end of an array of pointers to CTableCell objects. An attacker can leverage this vulnerability to execute code under the context of the current process.
