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

Microsoft Windows 2000 before Update Rollup 1 for SP4 does not record the IP address of a Windows Terminal Services client in a security log event if the client connects successfully, which could make it easier for attackers to escape detection.Show less

Microsoft Windows 2000 before Update Rollup 1 for SP4 allows a local administrator to unlock a computer even if it has been locked by a domain administrator, which allows the local administrator to access the session as the domain administrator.Show less

Microsoft Windows 2000 before Update Rollup 1 for SP4 does not apply group policies if the user logs on using UPN credentials with a trailing dot, which prevents Windows 2000 from finding the correct domain controller and could allow the user to bypass intended restrictions.Show less

The WideCharToMultiByte function in Microsoft Windows 2000 before Update Rollup 1 for SP4 does not properly convert strings with Japanese composite characters in the last character, which could prevent the string from being null terminated and lead to data corruption or enable buffer overflow attacks.Show less

Microsoft Windows 2000 before Update Rollup 1 for SP4 records Event ID 1704 to indicate that Group Policy security settings were successfully updated, even when the processing fails such as when Ntuser.pol cannot be accessed, which could cause system administrators to believe that the system is compliant with the specified settings.Show less

The LDAP client on Microsoft Windows 2000 before Update Rollup 1 for SP4 accepts certificates using LDAP Secure Sockets Layer (LDAPS) even when the Certificate Authority (CA) is not trusted, which could allow attackers to trick users into believing that they are accessing a trusted site.Show less

Microsoft Windows 2000 before Update Rollup 1 for SP4, when the "audit directory service access" policy is enabled, does not record a 565 event message for File Delete Child operations on an Active Directory object in the security event log, which could allow attackers to conduct unauthorized activities without detection.Show less

The SECEDIT command on Microsoft Windows 2000 before Update Rollup 1 for SP4, when using a security template to set Access Control Lists (ACLs) on folders, does not apply ACLs on folders that are listed after a long folder entry, which could result in less secure permissions than specified by the template.Show less

Unquoted Windows search path vulnerability in Microsoft AntiSpyware might allow local users to execute code via a malicious c:\program.exe file, which is run by AntiSpywareMain.exe when it attempts to execute gsasDtServ.exe. NOTE: it is not clear whether this overlaps CVE-2005-2940.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

Microsoft IIS 5.1 and 6 allows remote attackers to spoof the SERVER_NAME variable to bypass security checks and conduct various attacks via a GET request with an http://localhost URI, which makes it appear as if the request is coming from localhost.Show less
