Various TCP/IP stacks and network applications allow remote attackers to cause a denial of service by flooding a target host with TCP connection attempts and completing the TCP/IP handshake without maintaining the connection state on the attacker host, aka the "NAPTHA" class of vulnerabilities. NOTE: this candidate may change significantly as the security community discusses the technical nature of NAPTHA and learns more about the affected applications. This candidate is at a higher level of abstraction than is typical for CVE.Show less

File and Print Sharing service in Windows 95, Windows 98, and Windows Me does not properly check the password for a file share, which allows remote attackers to bypass share access controls by sending a 1-byte password that matches the first character of the real password, aka the "Share Level Password" vulnerability.Show less

The web-based folder display capability in Microsoft Internet Explorer 5.5 on Windows 98 allows local users to insert Trojan horse programs by modifying the Folder.htt file and using the InvokeVerb method in the ShellDefView ActiveX control to specify a default execute option for the first file that is listed in the folder.Show less

The IPX protocol implementation in Microsoft Windows 95 and 98 allows remote attackers to cause a denial of service by sending a ping packet with a source IP address that is a broadcast address, aka the "Malformed IPX Ping Packet" vulnerability.Show less

Interactions between the CIFS Browser Protocol and NetBIOS as implemented in Microsoft Windows 95, 98, NT, and 2000 allow remote attackers to modify dynamic NetBIOS name cache entries via a spoofed Browse Frame Request in a unicast or UDP broadcast datagram.Show less

Windows 95, Windows 98, Windows 2000, Windows NT 4.0, and Terminal Server systems allow a remote attacker to cause a denial of service by sending a large number of identical fragmented IP packets, aka jolt2 or the "IP Fragment Reassembly" vulnerability.Show less

The default configuration for the domain name resolver for Microsoft Windows 98, NT 4.0, 2000, and XP sets the QueryIpMatching parameter to 0, which causes Windows to accept DNS updates from hosts that it did not query, which allows remote attackers to poison the DNS cache.Show less

The Windows help system can allow a local user to execute commands as another user by editing a table of contents metafile with a .CNT extension and modifying the topic action to include the commands to be executed when the .hlp file is accessed.Show less
