This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of 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 unusual values for the layout-grid-char style property. Specific values may result in the destruction of a tree node that is still in use during the rendering of the HTML page. The resulting use-after-free vulnerability can be leveraged to achieve remote code execution.
