The following is a Security Bulletin from the Microsoft Product Security Notification Service. Please do not reply to this message, as it was sent from an unattended mailbox. ******************************** -----BEGIN PGP SIGNED MESSAGE----- - ---------------------------------------------------------------------- Title: Patch Available for "Windows Media Player Skins File Download" Vulnerability Date: February 14, 2001 Software: Windows Media Player 7 Impact: Run arbitrary code Bulletin: MS01-010 Microsoft encourages customers to review the Security Bulletin at: http://www.microsoft.com/technet/security/bulletin/MS01-010.asp. - ---------------------------------------------------------------------- Issue: ====== Windows Media Player 7 introduced a feature called "skins", that allows customization of the look and feel of Windows Media Player. If a Windows Media Player skin (.WMZ) file were downloaded from a malicious web site it could potentially be used to run Java code to read and browse files on a local machine. The vulnerability stems from the fact that "skins" are downloaded to a known location on a victim's computer and are stored in a .zip package. If the .zip package contained a Java class (.class) file, any Java code in this class could be executed under the local computer security zone. If a Windows Media Player skin (.WMZ) file were downloaded from a malicious web site, it could potentially cause the deployment of zipped Java code to a known location on the visiting user's machine. Since the Java code would reside in a known location on the machine, script hosted on a hostile web site or embedded in a hostile HTML mail message could potentially invoke the script in the local computer security zone to take arbitrary action on the user's machine. Mitigating Factors: ==================== - Disable the running of unsigned Java content - Be wary of visiting malicious web sites or opening e-mail from unknown sources Patch Availability: =================== - A patch is available to fix this vulnerability. Please read the Security Bulletin http://www.microsoft.com/technet/security/bulletin/ms01-010.asp for information on obtaining this patch. - --------------------------------------------------------------------- THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
