Two vulnerabilities in Microsoft Virtual Machine (VM) up to and including build 5.0.3805, as used in Internet Explorer and other applications, allow remote attackers to read files via a Java applet with a spoofed location in the CODEBASE parameter in the APPLET tag, possibly due to a parsing error.

The Java Database Connectivity (JDBC) APIs in Microsoft Virtual Machine (VM) 5.0.3805 and earlier allow remote attackers to bypass security checks and access database contents via an untrusted Java applet.

Microsoft Virtual Machine (VM) build 5.0.3805 and earlier allows remote attackers to determine a local user's username via a Java applet that accesses the user.dir system property, aka "User.dir Exposure Vulnerability."

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.

Remote Data Protocol (RDP) version 5.0 in Microsoft Windows 2000 and RDP 5.1 in Windows XP does not encrypt the checksums of plaintext session data, which could allow a remote attacker to determine the contents of encrypted sessions via sniffing, aka "Weak Encryption in RDP Protocol."

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."

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".

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.

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.

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.

Windows NT allows remote attackers to list all users in a domain by obtaining the domain SID with the LsaQueryInformationPolicy policy function via a null session and using the SID to list the users.

Windows NT 4.0 SP 6a allows a local user with write access to winnt/system32 to cause a denial of service (crash in lsass.exe) by running the NT4ALL exploit program in 'SPECIAL' mode.

Windows 2000 and Windows NT allows local users to cause a denial of service (reboot) by executing a command at the command prompt and pressing the F7 and enter keys several times while the command is executing, possibly related to an exception handling error in csrss.exe.

Buffer overflow in Microsoft Visual Studio RAD Support sub-component of FrontPage Server Extensions allows remote attackers to execute arbitrary commands via a long registration request (URL) to fp30reg.dll.

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.

Windows NT 4.0 and Windows 2000 hosts allow remote attackers to cause a denial of service (unavailable connections) by sending multiple SMB SMBnegprots requests but not reading the response that is sent back.

Buffer overflows in Microsoft Network Monitor (Netmon) allow remote attackers to execute arbitrary commands via a long Browser Name in a CIFS Browse Frame, a long SNMP community name, or a long username or filename in an SMB session, aka the "Netmon Protocol Parsing" vulnerability. NOTE: It is highly likely that this candidate will be split into multiple candidates.

Windows NT Service Control Manager (SCM) allows remote attackers to cause a denial of service via a malformed argument in a resource enumeration request.

The rdisk utility in Microsoft Terminal Server Edition and Windows NT 4.0 stores registry hive information in a temporary file with permissions that allow local users to read it, aka the "RDISK Registry Enumeration File" vulnerability.
