Microsoft has released a patch that eliminates a security vulnerability that could enable a malicious user to create an e-mail attachment that could cause your e-mail program to shut down. This situation occurs when you close the affected e-mail message, resulting in the following error message: If you click Details, you may receive the following error message: NOTE: This vulnerability does not occur unless both Windows Media Player 7 and Outlook or Outlook Express are installed on your computer. This vulnerability does not cause any lasting effects. You can resume normal operation by restarting your mail program and deleting the affected mail. Although the affected ActiveX control (OCX) is associated with Windows Media Player, it poses no threat to Windows Media Player; the vulnerability can be used only against e-mail clients.
