Vulnerabilities (CVE)

Buffer overflow in the COM Internet Services and in the RPC over HTTP Proxy components for Microsoft Windows NT Server 4.0, NT 4.0 Terminal Server Edition, 2000, XP, and Server 2003 allows remote attackers to cause a denial of service via a crafted request.

Denial of service in Windows NT DNS servers through malicious packet which contains a response to a query that wasn't made.

The getCanonicalPath function in Windows NT 4.0 may free memory that it does not own and cause heap corruption, which allows attackers to cause a denial of service (crash) via requests that cause a long file name to be passed to getCanonicalPath, as demonstrated on the IBM JVM using a long string to the java.io.getCanonicalPath Java method.

Denial of service in RPCSS.EXE program (RPC Locator) in Windows NT.

A later variation on the Teardrop IP denial of service attack, a.k.a. Teardrop-2.

Heap-based buffer overflow in the Hrtbeat.ocx (Heartbeat) ActiveX control for Internet Explorer 5.01 through 6, when users who visit online gaming sites that are associated with MSN, allows remote attackers to execute arbitrary code via the SetupData parameter.

The system root folder of Microsoft Windows 2000 has default permissions of Everyone group with Full access (Everyone:F) and is in the search path when locating programs during login or application launch from the desktop, which could allow attackers to gain privileges as other users via Trojan horse programs.

Network Dynamic Data Exchange (NetDDE) services for Microsoft Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows attackers to remotely execute arbitrary code or locally gain privileges via a malicious message or application that involves an "unchecked buffer," possibly a buffer overflow.

A Windows NT user can use SUBST to map a drive letter to a folder, which is not unmapped after the user logs off, potentially allowing that user to modify the location of folders accessed by later users.

Windows NT TCP/IP processes fragmented IP packets improperly, causing a denial of service.

Buffer overflow in RegAPI.DLL used by Windows NT 4.0 Terminal Server allows remote attackers to execute arbitrary commands via a long username, aka the "Terminal Server Login Buffer Overflow" vulnerability.

Microsoft Internet Explorer 6.0 on Windows NT 4.0 SP6a, Windows 2000 SP4, Windows XP SP1, Windows XP SP2, and Windows Server 2003 SP1 allows remote attackers to cause a denial of service (client crash) via a certain combination of a malformed HTML file and a CSS file that triggers a null dereference, probably related to rendering of a DIV element that contains a malformed IMG tag, as demonstrated by IEcrash.htm and IEcrash.rar.

A Windows NT system's registry audit policy does not log an event success or failure for non-critical registry keys.

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.

The Windows NT guest account is enabled.

Windows NT does not properly download a system policy if the domain user logs into the domain with a space at the end of the domain name.

Heap-based buffer overflow in the Distributed Component Object Model (DCOM) interface in the RPCSS Service allows remote attackers to execute arbitrary code via a malformed DCERPC DCOM object activation request packet with modified length fields, a different vulnerability than CVE-2003-0352 (Blaster/Nachi) and CVE-2003-0528.

The TCP/IP stack in multiple operating systems allows remote attackers to cause a denial of service (CPU consumption) via a TCP packet with the correct sequence number but the wrong Acknowledgement number, which generates a large number of "keep alive" packets. NOTE: some followups indicate that this issue could not be replicated.

The Server Message Block (SMB) implementation for Windows NT 4.0, 2000, XP, and Server 2003 does not properly validate certain SMB packets, which allows remote attackers to execute arbitrary code via Transaction responses containing (1) Trans or (2) Trans2 commands, aka the "Server Message Block Vulnerability," and as demonstrated using Trans2 FIND_FIRST2 responses with large file name length fields.

A Windows NT user has inappropriate rights or privileges, e.g. Act as System, Add Workstation, Backup, Change System Time, Create Pagefile, Create Permanent Object, Create Token Name, Debug, Generate Security Audit, Increase Priority, Increase Quota, Load Driver, Lock Memory, Profile Single Process, Remote Shutdown, Replace Process Token, Restore, System Environment, Take Ownership, or Unsolicited Input.

The RPC Runtime Library for Microsoft Windows NT 4.0 allows remote attackers to read active memory or cause a denial of service (system crash) via a malicious message, possibly related to improper length values.

Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.

Buffer overflow in the SMB capability for Microsoft Windows XP, 2000, and NT allows remote attackers to cause a denial of service and possibly execute arbitrary code via an SMB packet that specifies a smaller buffer length than is required.

Windows NT 4.0 allows local users to cause a denial of service via a user mode application that closes a handle that was opened in kernel mode, which causes a crash when the kernel attempts to close the handle.

The screen saver in Windows NT does not verify that its security context has been changed properly, allowing attackers to run programs with elevated privileges.

RPC endpoint mapper in Windows NT 4.0 allows remote attackers to cause a denial of service (loss of RPC services) via a malformed request.

The PATH in Windows NT includes the current working directory (.), which could allow local users to gain privileges by placing Trojan horse programs with the same name as commonly used system programs into certain directories.

A Windows NT administrator account has the default name of Administrator.

A version of finger is running that exposes valid user information to any entity on the network.

The logging capability for unicast and multicast transmissions in the ISAPI extension for Microsoft Windows Media Services in Microsoft Windows NT 4.0 and 2000, nsiislog.dll, allows remote attackers to cause a denial of service in Internet Information Server (IIS) and execute arbitrary code via a certain network request.

IIS 4.0 allows local users to bypass the "User cannot change password" policy for Windows NT by directly calling .htr password changing programs in the /iisadmpwd directory, including (1) aexp2.htr, (2) aexp2b.htr, (3) aexp3.htr , or (4) aexp4.htr.

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 ...
