NT Virtual DOS Machine (NTVDM.EXE) in Windows 2000, NT and XP does not verify user execution permissions for 16-bit executable files, which allows local users to bypass the loader and execute arbitrary programs.

WebSite Pro 3.1.11.0 on Windows allows remote attackers to read script source code for files with extensions greater than 3 characters via a URL request that uses the equivalent 8.3 file name.

Buffer overflow in the Windows Shell function in Microsoft Windows XP allows remote attackers to execute arbitrary code via an .MP3 or .WMA audio file with a corrupt custom attribute, aka "Unchecked Buffer in Windows Shell Could Enable System Compromise."

The SMB signing capability in the Server Message Block (SMB) protocol in Microsoft Windows 2000 and Windows XP allows attackers to disable the digital signing settings in an SMB session to force the data to be sent unsigned, then inject data into the session without detection, e.g. by modifying group policy information sent from a domain controller.

Microsoft Windows 98 and Windows NT 4.0 do not properly verify the Basic Constraints of digital certificates, allowing remote attackers to execute code, aka "New Variant of Certificate Validation Flaw Could Enable Identity Spoofing" (CAN-2002-0862).

The system root folder of Microsoft Windows 2000 has default permissions of Everyone group with Full access (Everyone:F) and is in the search path when locating programs during login or application launch from the desktop, which could allow attackers to gain privileges as other users via Trojan horse programs.

NetDDE Agent on Windows NT 4.0, 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows local users to execute arbitrary code as LocalSystem via "shatter" style attack by sending a WM_COPYDATA message followed by a WM_TIMER message, as demonstrated by GetAd, aka "Flaw in Windows WM_TIMER Message Handling Could Enable Privilege Elevation."

Buffer overflow in Microsoft PPTP Service on Windows XP and Windows 2000 allows remote attackers to cause a denial of service (hang) and possibly execute arbitrary code via a certain PPTP packet with malformed control data.

Memory leak in the SNMP LAN Manager (LANMAN) MIB extension for Microsoft Windows 2000 before SP3, when the Print Spooler is not running, allows remote attackers to cause a denial of service (memory consumption) via a large number of GET or GETNEXT requests.

Remote Data Protocol (RDP) version 5.0 in Microsoft Windows 2000 and RDP 5.1 in Windows XP does not encrypt the checksums of plaintext session data, which could allow a remote attacker to determine the contents of encrypted sessions via sniffing, aka "Weak Encryption in RDP Protocol."

The Remote Data Protocol (RDP) version 5.1 in Microsoft Windows XP allows remote attackers to cause a denial of service (crash) when Remote Desktop is enabled via a PDU Confirm Active data packet that does not set the Pattern BLT command, aka "Denial of Service in Remote Desktop."

Buffer overflow in MySQL daemon (mysqld) before 3.23.50, and 4.0 beta before 4.02, on the Win32 platform, allows local users to execute arbitrary code via a long "datadir" parameter in the my.ini initialization file, whose permissions on Windows allow Full Control to the Everyone group.

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."

The Sun Microsystems RPC library Services for Unix 3.0 Interix SD, as implemented on Microsoft Windows NT4, 2000, and XP, allows remote attackers to cause a denial of service (service hang) via malformed packet fragments, aka "Improper parameter size check leading to denial of service."

An input validation error in the Sun Microsystems RPC library Services for Unix 3.0 Interix SD, as implemented on Microsoft Windows NT4, 2000, and XP, allows remote attackers to cause a denial of service via malformed fragmented RPC client packets, aka "Denial of service by sending an invalid RPC request."

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.

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."

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.

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.
