USSR Advisory Code: USSR-2000053

Release Date:
September 26, 2000

Systems Affected:
Outlook 2000
Microsoft Windows Media Player 7

The USSR Team has found a problem in the Windows Media Player 7 ActiveX control, which could be used in a denial of service attack against RTF-enabled e-mail clients such as Outlook 2000 and Outlook Express.

If the affected control were programmatically embedded into an RTF mail and then sent to another user, the user's mail client would fail when he closed/moved the mail.

We take no responsibility for this code. It is for educational purposes only.
