Buffer overflow in the DNS Client service in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allows remote attackers to execute arbitrary code via a crafted record response. NOTE: while MS06-041 implies that there is a single issue, there are multiple vectors, and likely multiple vulnerabilities, related to (1) a heap-based buffer overflow in a DNS server response to the client, (2) a DNS server response with malformed ATMA records, and (3) a length miscalculation in TXT, HINFO, X25, and ISDN records.

Unspecified vulnerability in Microsoft Windows 2000 SP4, XP SP1 and SP2, Server 2003 and 2003 SP1, allows remote attackers to execute arbitrary code via unspecified vectors involving unhandled exceptions, memory resident applications, and incorrectly "unloading chained exception."

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.

** 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."

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.

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 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."

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."

The Server Message Block (SMB) driver (MRXSMB.SYS) in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 and earlier allows local users to cause a denial of service (hang) by calling the MrxSmbCscIoctlCloseForCopyChunk with the file handle of the shadow device, which results in a deadlock, aka the "SMB Invalid Handle 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 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.

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.

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.

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.

The default configuration of the DNS Server service on Windows Server 2003 and Windows 2000, and the Microsoft DNS Server service on Windows NT 4.0, allows recursive queries and provides additional delegation information to arbitrary IP addresses, which allows remote attackers to cause a denial of service (traffic amplification) via DNS queries with spoofed source IP addresses.

Heap-based buffer overflow in the bitmap processing routine in Microsoft Windows Media Player 7.1 on Windows 2000 SP4, Media Player 9 on Windows 2000 SP4 and XP SP1, and Media Player 10 on XP SP1 and SP2 allows remote attackers to execute arbitrary code via a crafted bitmap (.BMP) file that specifies a size of 0 but contains additional data.

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.

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.
