A 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.
