Vulnerability Details


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 in the 'onpropertychange' user callback function for the document.title. If the function changes the document in the callback function by using, for example, a document.write call, this can result in a use-after-free vulnerability. This can lead to remote code execution under the context of the program.

Microsoft has issued an update to correct this vulnerability. More details can be found at:
