The server driver (srv.sys) in Microsoft Windows NT 4.0, 2000, XP, and Server 2003 allows remote attackers to cause a denial of service (system crash) via an SMB_COM_TRANSACTION SMB message that contains a string without null character termination, which leads to a NULL dereference in the ExecuteTransaction function, possibly related to an "SMB PIPE," aka the "Mailslot DOS" vulnerability. NOTE: the name "Mailslot DOS" was derived from incomplete initial research; the vulnerability is not associated with a mailslot.

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.

Heap-based buffer overflow in the Server Service (SRV.SYS driver) in Microsoft Windows 2000 SP4, XP SP1 and SP2, Server 2003 up to SP1, and other products, allows remote attackers to execute arbitrary code via crafted first-class Mailslot messages that triggers memory corruption and bypasses size restrictions on second-class Mailslot messages.

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 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 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 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."

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.

Buffer overflow in the plug-in for Microsoft Windows Media Player (WMP) 9 and 10, when used in browsers other than Internet Explorer and set as the default application to handle media files, allows remote attackers to execute arbitrary code via HTML with an EMBED element containing a long src attribute.

An unspecified Microsoft WMF parsing application, as used in Internet Explorer 5.01 SP4 on Windows 2000 SP4, and 5.5 SP2 on Windows Millennium, and possibly other versions, allows attackers to cause a denial of service (crash) and possibly execute code via a crafted WMF file with a manipulated WMF header size, possibly involving an integer overflow, a different vulnerability than CVE-2005-4560, and aka "WMF Image Parsing Memory Corruption Vulnerability."
