Windows 2000 Terminal Services

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."Show less

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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

Two vulnerabilities in Microsoft Virtual Machine (VM) up to and including build 5.0.3805, as used in Internet Explorer and other applications, allow remote attackers to read files via a Java applet with a spoofed location in the CODEBASE parameter in the APPLET tag, possibly due to a parsing error.Show less

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.Show less

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.Show less

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."Show less

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.Show less

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."Show less

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."Show less
