-- 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.
