Microsoft Virtual Machine (VM) build 5.0.3805 and earlier allows remote attackers to determine a local user's username via a Java applet that accesses the user.dir system property, aka "User.dir Exposure Vulnerability."

Microsoft Virtual Machine (VM) up to and including build 5.0.3805 allows remote attackers to execute arbitrary code by including a Java applet that invokes COM (Component Object Model) objects in a web site or an HTML mail.

The Java Database Connectivity (JDBC) APIs in Microsoft Virtual Machine (VM) 5.0.3805 and earlier allow remote attackers to bypass security checks and access database contents via an untrusted Java applet.

The Compressed Folders feature in Microsoft Windows 98 with Plus! Pack, Windows Me, and Windows XP does not properly check the destination folder during the decompression of ZIP files, which allows attackers to place an executable file in a known location on a user's system, aka "Incorrect Target Path for Zipped File Decompression."

Buffer overflow in the HTML Help ActiveX Control (hhctrl.ocx) in Microsoft Windows 98, 98 Second Edition, Millennium Edition, NT 4.0, NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows remote attackers to execute code via (1) a long parameter to the Alink function, or (2) script containing a long argument to the showHelp function.

The HTML Help facility in Microsoft Windows 98, 98 Second Edition, Millennium Edition, NT 4.0, NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP uses the Local Computer Security Zone when opening .chm files from the Temporary Internet Files folder, which allows remote attackers to execute arbitrary code via HTML mail that references or inserts a malicious .chm file containing shortcuts that can be executed, aka "Code Execution via Compiled HTML Help File."

Buffer overflow in the ZIP capability for multiple products allows remote attackers to cause a denial of service or execute arbitrary code via ZIP files containing entries with long filenames, including (1) Microsoft Windows 98 with Plus! Pack, (2) Windows XP, (3) Windows ME, (4) Lotus Notes R4 through R6 (pre-gold), (5) Verity KeyView, and (6) Stuffit Expander before 7.0.

The (1) CertGetCertificateChain, (2) CertVerifyCertificateChainPolicy, and (3) WinVerifyTrust APIs within the CryptoAPI for Microsoft products including Microsoft Windows 98 through XP, Office for Mac, Internet Explorer for Mac, and Outlook Express for Mac, do not properly verify the Basic Constraints of intermediate CA-signed X.509 certificates, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack for SSL sessions, as originally reported for Internet Explorer and IIS.

Unknown vulnerability in the Certificate Enrollment ActiveX Control in Microsoft Windows 98, Windows 98 Second Edition, Windows Millennium, Windows NT 4.0, Windows 2000, and Windows XP allow remote attackers to delete digital certificates on a user's system via HTML.

Microsoft Windows Media Player versions 6.4 and 7.1 and Media Player for Windows XP allow remote attackers to bypass Internet Explorer's (IE) security mechanisms and run code via an executable .wma media file with a license installation requirement stored in the IE cache, aka the "Cache Path Disclosure via Windows Media Player".
