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 CSS stylesheets. The issue lies in the failure to properly clone the properties within a stylesheet that is referenced multiple times. An attacker can leverage this vulnerability to execute code under the context of the current process.
