VULNERABILITY DETAILS

This vulnerability allows 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 in routines responsible for the on-demand installation of Internet Explorer language packs. A race condition may occur when a web page contains several pieces of content written in a language not currently supported by any of the installed language packs. In some cases, this race condition results in exploitable memory corruption that can be leveraged to execute arbitrary code.
