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 handling of CMarkup objects. The issue lies in the failure to properly initialize a variable prior to using it, leading to memory corruption. An attacker can leverage this vulnerability to execute code under the context of the current process.
