Double free vulnerability in Microsoft Windows 2000, XP, 2003, and Vista allows local users to gain privileges by calling the MessageBox function with a MBSERVICENOTIFICATION message with crafted data, which sends a HardError message to Client/Server Runtime Server Subsystem (CSRSS) process, which is not properly handled when invoking the UserHardError and GetHardErrorText functions in WINSRV.DLL.
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 TCP/IP stack in multiple operating systems allows remote attackers to cause a denial of service (CPU consumption) via a TCP packet with the correct sequence number but the wrong Acknowledgement number, which generates a large number of "keep alive" packets. NOTE: some followups indicate that this issue could not be replicated.

DISPUTED Microsoft Windows NT 4.0, Windows 2000, Windows XP, and Windows Small Business Server 2003 allow remote attackers to cause a denial of service (IP stack hang) via a continuous stream of packets on TCP port 135 that have incorrect TCP header checksums and random numbers in certain TCP header fields, as demonstrated by the Achilles Windows Attack Tool. NOTE: the researcher reports that the Microsoft Security Response Center has stated "Our investigation which has included code review, review of the TCPDump, and attempts on reproing the issue on multiple fresh installs of various Windows Operating Systems have all resulted in non confirmation."
Buffer overflow in Windows Explorer (explorer.exe) on Windows XP and 2003 allows user-assisted attackers to cause a denial of service (repeated crash) and possibly execute arbitrary code via a .url file with an InternetShortcut tag containing a long URL and a large number of "file:" specifiers.
Buffer overflow in the TCP/IP Protocol driver in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 and earlier allows remote attackers to execute arbitrary code via unknown vectors related to IP source routing.
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."
Buffer overflow in the ART Image Rendering component (jgdw400.dll) in Microsoft Windows XP SP1 and Sp2, Server 2003 SP1 and earlier, and Windows 98 and Me allows remote attackers to execute arbitrary code via a crafted ART image that causes heap corruption.
Buffer overflow in the Routing and Remote Access service (RRAS) 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," aka the "RRAS Memory Corruption 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 JScript 5.1, 5.5, and 5.6 on Windows 2000 SP4, and 5.6 on Windows XP, Server 2003, Windows 98 and Windows Me, will "release objects early" in certain cases, which results in memory corruption and allows remote attackers to execute arbitrary code.
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.
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.
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."
