Buffer overflow in the Remote Access Connection Manager service (RASMAN) service in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 and earlier allows remote unauthenticated or authenticated attackers to execute arbitrary code via certain crafted "RPC related requests," that lead to registry corruption and stack corruption, aka the "RASMAN Registry Corruption Vulnerability."

Microsoft Distributed Transaction Coordinator (MSDTC) for Windows NT 4.0, 2000 SP4, XP SP1 and SP2, and Server 2003 allows remote attackers to cause a denial of service (crash) via a BuildContextW request with a large (1) UuidString or (2) GuidIn of a certain length, which causes an out-of-range memory access, aka the MSDTC Denial of Service Vulnerability. NOTE: this is a variant of CVE-2005-2119.

Heap-based buffer overflow in the CRpcIoManagerServer::BuildContext function in msdtcprx.dll for Microsoft Distributed Transaction Coordinator (MSDTC) for Windows NT 4.0 and Windows 2000 SP2 and SP3 allows remote attackers to execute arbitrary code via a long fifth argument to the BuildContextW or BuildContext opcode, which triggers a bug in the NdrAllocate function, aka the MSDTC Invalid Memory Access Vulnerability.

Unspecified vulnerability in Windows Explorer in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allows remote attackers to execute arbitrary code via attack vectors involving COM objects and "crafted files and directories," aka the "Windows Shell Vulnerability."

Heap-based buffer overflow in Microsoft Windows Help winhlp32.exe allows user-assisted attackers to execute arbitrary code via crafted embedded image data in a .hlp file.

Microsoft Windows XP SP1 and SP2, and Server 2003 up to SP1, allows remote attackers to cause a denial of service (hang) via an IGMP packet with an invalid IP option, aka the "IGMP v3 DoS Vulnerability."

Buffer overflow in the Web Client service (WebClnt.dll) for Microsoft Windows XP SP1 and SP2, and Server 2003 up to SP1, allows remote authenticated users or Guests to execute arbitrary code via crafted RPC requests, a different vulnerability than CVE-2005-1207.

The ShellAbout API call in Korean Input Method Editor (IME) in Korean versions of Microsoft Windows XP SP1 and SP2, Windows Server 2003 up to SP1, and Office 2003, allows local users to gain privileges by launching the "shell about dialog box" and clicking the "End-User License Agreement" link, which executes Notepad with the privileges of the program that displays the about box.

Heap-based buffer overflow in T2EMBED.DLL in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 up to SP1, Windows 98, and Windows ME allows remote attackers to execute arbitrary code via an e-mail message or web page with a crafted Embedded Open Type (EOT) web font that triggers the overflow during decompression.

Microsoft Windows Graphics Rendering Engine (GRE) allows remote attackers to corrupt memory and cause a denial of service (crash) via a WMF file containing (1) ExtCreateRegion or (2) ExtEscape function calls with arguments with inconsistent lengths.

The Windows Graphical Device Interface library (GDI32.DLL) in Microsoft Windows allows remote attackers to execute arbitrary code via a Windows Metafile (WMF) format image with a crafted SETABORTPROC GDI Escape function call, related to the Windows Picture and Fax Viewer (SHIMGVW.DLL), a different vulnerability than CVE-2005-2123 and CVE-2005-2124, and as originally discovered in the wild on unionseek.com.

DISPUTED 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 routine. NOTE: followup posts have disputed this issue, saying that if a user already has privileges to write to a process, then other functions could be called or the process could be terminated using PROCESSTERMINATE.

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 table lookups.

Unknown vulnerability in the PKINIT Protocol for Microsoft Windows 2000, Windows XP, and Windows Server 2003 could allow a local user to obtain information and spoof a server via a man-in-the-middle (MITM) attack between a client and a domain controller when PKINIT smart card authentication is being used.

Buffer overflow in a certain USB driver, as used on Microsoft Windows, allows attackers to execute arbitrary code.

The Telnet client for Microsoft Windows XP, Windows Server 2003, and Windows Services for UNIX allows remote attackers to read sensitive environment variables via the NEW-ENVIRON option with a SEND ENVUSERVAR command.

Integer overflow in Microsoft Windows 98, 2000, XP SP2 and earlier, and Server 2003 SP1 and earlier allows remote attackers to execute arbitrary code via a crafted compiled Help (.CHM) file with a large size field that triggers a heap-based buffer overflow, as demonstrated using a "ms-its:" URL in Internet Explorer.
