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.

The specific flaw exists when parsing the jscript keyword "arguments". Because the arguments object is not available until a certain time, invoking it can result in memory corruption. Successful exploitation of this vulnerability can lead to a remote system compromise under the credentials of the current user.
