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.

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.

NMPI (Name Management Protocol on IPX) listener in Microsoft NWLink does not properly filter packets from a broadcast address, which allows remote attackers to cause a broadcast storm and flood the network.

NETBIOS client in Windows 95 and Windows 98 allows a remote attacker to cause a denial of service by changing a file sharing service to return an unknown driver type, which causes the client to crash.

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.

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.

Windows 95 and Windows 98 do not properly process spoofed ARP packets, which allows remote attackers to overwrite static entries in the cache table.

A system does not present an appropriate legal message or warning to a user who is accessing it.

The CIFS Computer Browser service allows remote attackers to cause a denial of service by sending a ResetBrowser frame to the Master Browser, aka the "ResetBrowser Frame" vulnerability.

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.

Windows 95 and Windows 98 allow a remote attacker to cause a denial of service via a NetBIOS session request packet with a NULL source name.

Microsoft Windows 9x operating systems allow an attacker to cause a denial of service via a pathname that includes file device names, aka the "DOS Device in Path Name" vulnerability.

Windows NT Autorun executes the autorun.inf file on non-removable media, which allows local attackers to specify an alternate program to execute when other users access a drive.

Buffer overflow in the SHGetPathFromIDList function of the Serv-U FTP server allows attackers to cause a denial of service by performing a LIST command on a malformed .lnk file.

Windows 95 uses weak encryption for the password list (.pwl) file used when password caching is enabled, which allows local users to gain privileges by decrypting the passwords.

Windows 95, when Remote Administration and File Sharing for NetWare Networks is enabled, creates a share (C$) when an administrator logs in remotely, which allows remote attackers to read arbitrary files by mapping the network drive.

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.

A legacy credential caching mechanism used in Windows 95 and Windows 98 systems allows attackers to read plaintext network passwords.

The networking software in Windows 95 and Windows 98 allows remote attackers to execute commands via a long file name string, aka the "File Access URL" vulnerability.

Buffer overflow in Microsoft Telnet client in Windows 95 and Windows 98 via a malformed Telnet argument.
