The net effect of the vulnerability is that it could enable a malicious user to create an e-mail that, when closed after being read, could cause the e-mail application to fail. Frequently asked questions regarding this vulnerability and the patch can be found at http://www.microsoft.com/technet/security/bulletin/fq00-068.asp Issue ===== OCX controls are containers that can hold multiple ActiveX controls. A particular OCX control, associated with Windows Media Player, could be used in a denial of service attack against RTF-enabled e-mail clients such as Outlook 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 the mail. The vulnerability would not cause any lasting effects. The user could resume normal operation by restarting the mail client and deleting the affected mail.
