Microsoft Windows 2003 Server 64-bit

Buffer overflow in the Server Service in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allows remote attackers, including anonymous users, to execute arbitrary code via a crafted RPC message, a different vulnerability than CVE-2006-1314.

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.

Integer overflow in DUNZIP32.DLL for Microsoft Windows XP, Windows XP 64-bit Edition, Windows Server 2003, and Windows Server 2003 64-bit Edition allows remote attackers to execute arbitrary code via compressed (zipped) folders that involve an "unchecked buffer" and improper length validation.

Buffer overflow in the Winsock API in Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allows remote attackers to execute arbitrary code via unknown vectors, aka "Winsock Hostname Vulnerability."

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.

The HTML Help ActiveX control (Hhctrl.ocx) in Microsoft Windows 2000 SP3, XP SP2 and Professional, 2003 SP1 allows remote attackers to execute arbitrary code via unspecified functions, related to uninitialized parameters.

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.

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 Vulnerability."

The Windows Internet Naming Service (WINS) in Windows NT Server 4.0 SP 6a, NT Terminal Server 4.0 SP 6, Windows 2000 Server SP3 and SP4, and Windows Server 2003 does not properly validate the computer name value in a WINS packet, which allows remote attackers to execute arbitrary code or cause a denial of service (server crash), which results in an "unchecked buffer" and possibly triggers a buffer overflow, aka the "Name Validation Vulnerability."

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 MRBP16::bCheckRecord.

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.

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

Buffer overflow in the HTML Converter (HTML32.cnv) on various Windows operating systems allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via cut-and-paste operation, as demonstrated in Internet Explorer 5.0 using a long "align" argument in an HR tag.

Integer overflow in the ReadWideString function in agentdpv.dll in Microsoft Agent on Microsoft Windows 2000 SP4, XP SP2, and Server 2003 up to SP1 allows remote attackers to execute arbitrary code via a large length value in an .ACF file, which results in a heap-based buffer overflow.

Heap-based buffer overflow in URLMON.DLL in Microsoft Internet Explorer 6 SP1 on Windows 2000 and XP SP1, with versions the MS06-042 patch before 20060912, allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a long URL in a GZIP-encoded website that was the target of an HTTP redirect, due to an incomplete fix for CVE-2006-3869.

Heap-based buffer overflow in the BERDecBitString function in Microsoft ASN.1 library (MSASN1.DLL) allows remote attackers to execute arbitrary code via nested constructed bit strings, which leads to a realloc of a non-null pointer and causes the function to overwrite previously freed memory, as demonstrated using a SPNEGO token with a constructed bit string during HTTP authentication, and a different vulnerability than CVE-2003-0818. NOTE: the researcher has claimed that MS:MS04-007 fixes this issue.

Buffer overflow in Microsoft Step-by-Step Interactive Training (orun32.exe) allows remote attackers to execute arbitrary code via a bookmark link file (.cbo, cbl, or .cbm extension) with a long User field.

VMware Workstation before 5.5.4, when running a 64-bit Windows guest on a 64-bit host, allows local users to "corrupt the virtual machine's register context" by debugging a local program and stepping into a "syscall instruction."

The Web Proxy Auto-Discovery (WPAD) feature in Microsoft Internet Explorer 6 and 7, when a primary DNS suffix with three or more components is configured, resolves an unqualified wpad hostname in a second-level domain outside this configured DNS domain, which allows remote WPAD servers to conduct man-in-the-middle (MITM) attacks.

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 Agent allows remote attackers to spoof trusted Internet content and execute arbitrary code by disguising security prompts on a malicious Web page.

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, which writes management data to memory outside of the allocated buffer.

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."

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.

The user interface in the Windows Firewall does not properly display certain malformed entries in the Windows Registry, which makes it easier for attackers with administrator privileges to hide activities if the administrator only uses the Windows Firewall interface to monitor exceptions. NOTE: the vendor disputes this issue, saying that since administrative privileges are already required, it is not a vulnerability. CVE has not yet formally decided if such "information hiding" issues should be included.
