Buffer overflow in SmartHTML Interpreter (shtml.dll) in Microsoft FrontPage Server Extensions (FPSE) 2000 and 2002 allows remote attackers to cause a denial of service (CPU consumption) or run arbitrary code, respectively, via a certain type of web file request.

Buffer overflow in the HTML Help ActiveX Control (hhctrl.ocx) in Microsoft Windows 98, 98 Second Edition, Millennium Edition, NT 4.0, NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP allows remote attackers to execute code via (1) a long parameter to the Alink function, or (2) script containing a long argument to the showHelp function.

The HTML Help facility in Microsoft Windows 98, 98 Second Edition, Millennium Edition, NT 4.0, NT 4.0 Terminal Server Edition, Windows 2000, and Windows XP uses the Local Computer Security Zone when opening .chm files from the Temporary Internet Files folder, which allows remote attackers to execute arbitrary code via HTML mail that references or inserts a malicious .chm file containing shortcuts that can be executed, aka "Code Execution via Compiled HTML Help File."

Unknown vulnerability in the Certificate Enrollment ActiveX Control in Microsoft Windows 98, Windows 98 Second Edition, Windows Millennium, Windows NT 4.0, Windows 2000, and Windows XP allow remote attackers to delete digital certificates on a user's system via HTML.

The (1) CertGetCertificateChain, (2) CertVerifyCertificateChainPolicy, and (3) WinVerifyTrust APIs within the CryptoAPI for Microsoft products including Microsoft Windows 98 through XP, Office for Mac, Internet Explorer for Mac, and Outlook Express for Mac, do not properly verify the Basic Constraints of intermediate CA-signed X.509 certificates, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack for SSL sessions, as originally reported for Internet Explorer and IIS.

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".

A handler routine for the Network Connection Manager (NCM) in Windows 2000 allows local users to gain privileges via a complex attack that causes the handler to run in the LocalSystem context with user-specified code.

Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including dietlibc, allows remote attackers to execute arbitrary code by passing a large number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd.

Microsoft Windows 2000 allows local users to bypass the policy that prohibits reusing old passwords by changing the current password before it expires, which does not enable the check for previous passwords.

Buffer overflow in Remote Access Service (RAS) phonebook for Windows NT 4.0, 2000, XP, and Routing and Remote Access Server (RRAS) allows local users to execute arbitrary code by modifying the rasphone.pbk file to use a long dial-up entry.

smss.exe debugging subsystem in Windows NT and Windows 2000 does not properly authenticate programs that connect to other programs, which allows local users to gain administrator or SYSTEM privileges by duplicating a handle to a privileged process, as demonstrated by DebPloit.

LANMAN service on Microsoft Windows 2000 allows remote attackers to cause a denial of service (CPU/memory exhaustion) via a stream of malformed data to microsoft-ds port 445.

The MSDTC (Microsoft Distributed Transaction Service Coordinator) for Microsoft Windows 2000, Microsoft IIS 5.0 and SQL Server 6.5 through SQL 2000 0.0 allows remote attackers to cause a denial of service (crash or hang) via malformed (random) input.

Windows 2000 allows local users to prevent the application of new group policy settings by opening Group Policy files with exclusive-read access.

Buffer overflow in Multiple UNC Provider (MUP) in Microsoft Windows operating systems allows local users to cause a denial of service or possibly gain SYSTEM privileges via a long UNC request.

Buffer overflow in Windows Shell (used as the Windows Desktop) allows local and possibly remote attackers to execute arbitrary code via a custom URL handler that has not been removed for an application that has been improperly uninstalled.

In Microsoft Windows NT and Windows 2000, a trusting domain that receives authorization information from a trusted domain does not verify that the trusted domain is authoritative for all listed SIDs, which allows remote attackers to gain Domain Administrator privileges on the trusting domain by injecting SIDs from untrusted domains into the authorization data that comes from from the trusted domain.

Buffer overflow in telnet server in Windows 2000 and Interix 2.2 allows remote attackers to execute arbitrary code via malformed protocol options.

Buffer overflow in SNMP agent service in Windows 95/98/98SE, Windows NT 4.0, Windows 2000, and Windows XP allows remote attackers to cause a denial of service or execute arbitrary code via a malformed management request. NOTE: this candidate may be split or merged with other candidates. This and other PROTOS-related candidates, especially CVE-2002-0012 and CVE-2002-0013, will be updated when more accurate information is available.

SMTP service in (1) Microsoft Windows 2000 and (2) Internet Mail Connector (IMC) in Exchange Server 5.5 does not properly handle responses to NTLM authentication, which allows remote attackers to perform mail relaying via an SMTP AUTH command using null session credentials.
