Vulnerabilidades

The thread termination routine in the kernel for Windows NT 4.0 and 2000 (NTOSKRNL.EXE) allows local users to modify kernel memory and execution flow via steps in which a terminating thread causes Asynchronous Procedure Call (APC) entries to free the wrong data, aka the "Windows Kernel Vulnerability."

NOTE: this issue has been disputed by third parties. Microsoft Windows XP, 2000, and 2003 allows local users to kill a writable process by using the CreateRemoteThread function with certain arguments on a process that has been opened using the OpenProcess function, possibly involving an invalid address for the start…

The SynAttackProtect protection in Microsoft Windows 2003 before SP1 and Windows 2000 before SP4 with Update Roll-up uses a hash of predictable data, which allows remote attackers to cause a denial of service (CPU consumption) via a flood of SYN packets that produce identical hash values, which slows down the hash…

Multiple integer overflows in the Graphics Rendering Engine (GDI32.DLL) in Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allow remote attackers to execute arbitrary code via crafted Windows Metafile (WMF) and Enhanced Metafile (EMF) format images that lead to heap-based buffer overflows, as demonstrated using…

Unspecified vulnerability in the Graphics Rendering Engine (GDI32.DLL) in Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1, related to "An unchecked buffer" and possibly buffer overflows, allows remote attackers to execute arbitrary code via a crafted Windows Metafile (WMF) format image, aka "Windows Metafile…

PNP_GetDeviceList (upnp_getdevicelist) in UPnP for Microsoft Windows 2000 SP4 and earlier, and possibly Windows XP SP1 and earlier, allows remote attackers to cause a denial of service (memory consumption) via a DCE RPC request that specifies a large output buffer size, a variant of CVE-2006-6296, and a different…

Windows Shell for Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 allows remote user-assisted attackers to execute arbitrary commands via a crafted shortcut (.lnk) file with long font properties that lead to a buffer overflow when the user views the file's properties using Windows Explorer, a different…

The FTP client in Windows XP SP1 and Server 2003, and Internet Explorer 6 SP1 on Windows 2000 SP4, when "Enable Folder View for FTP Sites" is enabled and the user manually initiates a file transfer, allows user-assisted, remote FTP servers to overwrite files in arbitrary locations via crafted filenames.

Windows Shell for Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 allows remote attackers to execute arbitrary commands via a shortcut (.lnk) file with long font properties that lead to a buffer overflow in the Client/Server Runtime Server Subsystem (CSRSS), a different vulnerability than CVE-2005-2118.

Web View in Windows Explorer on Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 does not properly handle certain HTML characters in preview fields, which allows remote user-assisted attackers to execute arbitrary code.

Stack-based buffer overflow in the Plug and Play (PnP) service (UMPNPMGR.DLL) in Microsoft Windows 2000 SP4, and XP SP1 and SP2, allows remote or local authenticated attackers to execute arbitrary code via a large number of "\" (backslash) characters in a registry key name, which triggers the overflow in a wsprintfW…

The Client Service for NetWare (CSNW) on Microsoft Windows 2000 SP4, XP SP1 and Sp2, and Server 2003 SP1 and earlier, allows remote attackers to execute arbitrary code due to an "unchecked buffer" when processing certain crafted network messages.

Buffer overflow in Collaboration Data Objects (CDO), as used in Microsoft Windows and Microsoft Exchange Server, allows remote attackers to execute arbitrary code when CDOSYS or CDOEX processes an e-mail message with a large header name, as demonstrated using the "Content-Type" string.

Distributed Transaction Controller in Microsoft Windows allows remote servers to cause a denial of service (MSDTC service hang) via a crafted Transaction Internet Protocol (TIP) message that causes DTC to repeatedly connect to a target IP and port number after an error occurs, aka the "Distributed TIP Vulnerability."

The MIDL_user_allocate function in the Microsoft Distributed Transaction Coordinator (MSDTC) proxy (MSDTCPRX.DLL) allocates a 4K page of memory regardless of the required size, which allows attackers to overwrite arbitrary memory locations using an incorrect size value that is provided to the NdrAllocate function,…

Distributed Transaction Controller in Microsoft Windows allows remote servers to cause a denial of service (MSDTC service exception and exit) via an "unexpected protocol command during the reconnection request," which is not properly handled by the Transaction Internet Protocol (TIP) functionality.

COM+ in Microsoft Windows does not properly "create and use memory structures," which allows local users or remote attackers to execute arbitrary code.

Microsoft Windows 2000 before Update Rollup 1 for SP4 does not apply group policies if the user logs on using UPN credentials with a trailing dot, which prevents Windows 2000 from finding the correct domain controller and could allow the user to bypass intended restrictions.

The SECEDIT command on Microsoft Windows 2000 before Update Rollup 1 for SP4, when using a security template to set Access Control Lists (ACLs) on folders, does not apply ACLs on folders that are listed after a long folder entry, which could result in less secure permissions than specified by the template.

Microsoft Windows 2000 before Update Rollup 1 for SP4 does not record the IP address of a Windows Terminal Services client in a security log event if the client connects successfully, which could make it easier for attackers to escape detection.

Microsoft Windows 2000 before Update Rollup 1 for SP4 allows users to log on to the domain, even when their password has expired, if the fully qualified domain name (FQDN) is 8 characters long.

Microsoft Windows 2000 before Update Rollup 1 for SP4 allows a local administrator to unlock a computer even if it has been locked by a domain administrator, which allows the local administrator to access the session as the domain administrator.

Microsoft Windows 2000 before Update Rollup 1 for SP4 records Event ID 1704 to indicate that Group Policy security settings were successfully updated, even when the processing fails such as when Ntuser.pol cannot be accessed, which could cause system administrators to believe that the system is compliant with the…

The LDAP client on Microsoft Windows 2000 before Update Rollup 1 for SP4 accepts certificates using LDAP Secure Sockets Layer (LDAPS) even when the Certificate Authority (CA) is not trusted, which could allow attackers to trick users into believing that they are accessing a trusted site.

The WideCharToMultiByte function in Microsoft Windows 2000 before Update Rollup 1 for SP4 does not properly convert strings with Japanese composite characters in the last character, which could prevent the string from being null terminated and lead to data corruption or enable buffer overflow attacks.
