Microsoft Windows XP and Windows 2000, when configured to send administrative alerts and the "Do not overwrite events (clear log manually)" option is set, does not notify the administrator when the log reaches its maximum size, which allows local users and remote attackers to avoid detection.

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.

The RPC component in Windows 2000, Windows NT 4.0, and Windows XP allows remote attackers to cause a denial of service (disabled RPC service) via a malformed packet to the RPC Endpoint Mapper at TCP port 135, which triggers a null pointer dereference.

Microsoft Windows XP Explorer allows attackers to execute arbitrary code via a HTML and script in a self-executing folder that references an executable file within the folder, which is automatically executed when a user accesses the folder.

Stack-based buffer overflow in the Plug and Play (PnP) service for Microsoft Windows 2000 and Windows XP Service Pack 1 allows remote attackers to execute arbitrary code via a crafted packet, and local users to gain privileges via a malicious application, as exploited by the Zotob (aka Mytob) worm.

Buffer overflow in SMB (Server Message Block) protocol in Microsoft Windows NT, Windows 2000, and Windows XP allows attackers to cause a denial of service (crash) via a SMB_COM_TRANSACTION packet with a request for the (1) NetShareEnum, (2) NetServerEnum2, or (3) NetServerEnum3, aka "Unchecked Buffer in Network Share Provider Can Lead to Denial of Service".

Windows XP with fast user switching and account lockout enabled allows local users to deny user account access by setting the fast user switch to the same user (self) multiple times, which causes other accounts to be locked out.

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 Compressed Folders feature in Microsoft Windows 98 with Plus! Pack, Windows Me, and Windows XP does not properly check the destination folder during the decompression of ZIP files, which allows attackers to place an executable file in a known location on a user's system, aka "Incorrect Target Path for Zipped File Decompression."

Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) by iterating over any native function, as demonstrated with the window.alert function, which triggers a null dereference.

Microsoft Windows XP Professional upgrade edition overwrites previously installed patches for Internet Explorer 6.0, leaving Internet Explorer unpatched.

Multiple integer overflows in Microsoft ASN.1 library (MSASN1.DLL), as used in LSASS.EXE, CRYPT32.DLL, and other Microsoft executables and libraries on Windows NT 4.0, 2000, and XP, allow remote attackers to execute arbitrary code via ASN.1 BER encodings with (1) very large length fields that cause arbitrary heap data to be overwritten, or (2) modified bit strings.

HyperTerminal application for Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 does not properly validate the length of a value that is saved in a session file, which allows remote attackers to execute arbitrary code via a malicious HyperTerminal session file (.ht), web site, or Telnet URL contained in an e-mail message, triggering a buffer overflow.

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.

Buffer overflow in the Windows Shell function in Microsoft Windows XP allows remote attackers to execute arbitrary code via an .MP3 or .WMA audio file with a corrupt custom attribute, aka "Unchecked Buffer in Windows Shell Could Enable System Compromise."

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 b ... 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.

CVE has not yet formally decided if such "information hiding" issues should be included.

The SMB signing capability in the Server Message Block (SMB) protocol in Microsoft Windows 2000 and Windows XP allows attackers to disable the digital signing settings in an SMB session to force the data to be sent unsigned, then inject data into the session without detection, e.g. by modifying group policy information sent from a domain controller.
