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

Remote attackers can perform a denial of service in Windows machines using malicious ARP packets, forcing a message box display for each packet or filling up log files.

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.

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.

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.

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.

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.

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.

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.

Microsoft Data Access Component Internet Publishing Provider 8.103.2519.0 and earlier allows remote attackers to bypass Security Zone restrictions via WebDAV requests.

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

Windows 95 and Windows 98 systems, when configured with multiple TCP/IP stacks bound to the same MAC address, allow remote attackers to cause a denial of service (traffic amplification) via a certain ICMP echo (ping) packet, which causes all stacks to send a ping response, aka TCP Chorusing.

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

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 remote attacker can disable the virus warning mechanism in Microsoft Excel 97.

Buffer overflow in the ZIP capability for multiple products allows remote attackers to cause a denial of service or execute arbitrary code via ZIP files containing entries with long filenames, including (1) Microsoft Windows 98 with Plus! Pack, (2) Windows XP, (3) Windows ME, (4) Lotus Notes R4 through R6 (pre-gold), (5) Verity KeyView, and (6) Stuffit Expander before 7.0.

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.

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 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.
