Windows 2003 Server

The Client Service for NetWare (CSNW) on Microsoft Windows 2000 SP4, XP SP1 and Sp2, and Server 2003 SP1 and earlier, allows remote attackers to execute arbitrary code due to an "unchecked buffer" when processing certain crafted network messages.Show less

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.Show less

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."Show less

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.Show less

CHKDSK in Microsoft Windows 2000 before Update Rollup 1 for SP4, Windows XP, and Windows Server 2003, when running in fix mode, does not properly handle security descriptors if the master file table contains a large number of files or if the descriptors do not satisfy certain NTFS conventions, which could cause ACLs for some files to be reverted to less secure defaults, or cause security descriptors to be removed.Show less

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.Show less

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.Show less

Buffer overflow in the Telephony Application Programming Interface (TAPI) for Microsoft Windows 98, Windows 98 SE, Windows ME, Windows 2000, Windows XP, and Windows Server 2003 allows attackers to elevate privileges or execute arbitrary code via a crafted message.Show less

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.Show less

Buffer overflow in the Server Message Block (SMB) functionality for Microsoft Windows 2000, XP SP1 and SP2, and Server 2003 and SP1 allows remote attackers to execute arbitrary code via unknown vectors, aka the "Server Message Block Vulnerability."Show less

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.Show less
