DESCRIPTION:
A vulnerability has been reported in Windows Media Player, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a use-after-free error in the
Windows Media Player ActiveX control when retrieving a codec for an
unknown fourCC compression code. This can be exploited by tricking a
user into accessing a web page hosting media content where the
control is removed from the page while the codec is requested from
Microsoft.

Successful exploitation allows execution of arbitrary code.
