The ByteCode Verifier component of Microsoft Virtual Machine (VM) build 5.0.3809 and earlier, as used in Windows and Internet Explorer, allows remote attackers to bypass security checks and execute arbitrary code via a malicious Java applet, aka "Flaw in Microsoft VM Could Enable System Compromise."
The RPC component in Windows 2000, Windows NT 4.0, and Windows XP allows remote attackers to cause a denial of service (disabled RPC service) via a malformed packet to the RPC Endpoint Mapper at TCP port 135, which triggers a null pointer dereference.
Buffer overflow in ntdll.dll on Microsoft Windows NT 4.0, Windows NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows remote attackers to execute arbitrary code, as demonstrated via a WebDAV request to IIS 5.0.
Integer overflow in JsArrayFunctionHeapSort function used by Windows Script Engine for JScript (JScript.dll) on various Windows operating system allows remote attackers to execute arbitrary code via a malicious web page or HTML e-mail that uses a large array index value that enables a heap-based buffer overflow attack.
Buffer overflow in the RPC Locator service for Microsoft Windows NT 4.0, Windows NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows local users to execute arbitrary code via an RPC call to the service containing certain parameter information.
Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets, as demonstrated by Etherleak.
Cross-site scripting vulnerability (XSS) in the missing template handler in Macromedia ColdFusion MX allows remote attackers to execute arbitrary script as other users by injecting script into the HTTP request for the name of a template, which is not filtered in the resulting 404 error message.
Microsoft Windows 2000 allows remote attackers to cause a denial of service (memory consumption) by sending a flood of empty TCP/IP packets with the ACK and FIN bits set to the NetBIOS port (TCP/139), as demonstrated by stream3.
Windows 2000 Terminal Services, when using the disconnect feature of the client, does not properly lock itself if it is left idle until the screen saver activates and the user disconnects, which could allow attackers to gain administrator privileges.
Microsoft Windows XP and Windows 2000, when configured to send administrative alerts and the "Do not overwrite events (clear log manually)" option is set, does not notify the administrator when the log reaches its maximum size, which allows local users and remote attackers to avoid detection.
