Buffer overflow in run-time linkers (1) ld.so or (2) ld-linux.so for Linux systems allows local users to gain privileges by calling a setuid program with a long program name (argv[0]) and forcing ld.so/ld-linux.so to report an error.
The campas CGI program provided with some NCSA web servers allows an attacker to execute arbitrary commands via encoded carriage return characters in the query string, as demonstrated by reading the password file.
Windows NT 4.0 before SP3 allows remote attackers to bypass firewall restrictions or cause a denial of service (crash) by sending improperly fragmented IP packets without the first fragment, which the TCP/IP stack incorrectly reassembles into a valid session.
websendmail in Webgais 1.0 allows a remote user to access arbitrary files and execute arbitrary code via the receiver parameter ($VAR_receiver variable).
JavaScript in Internet Explorer 3.x and 4.x, and Netscape 2.x, 3.x and 4.x, allows remote attackers to monitor a user's web activities, aka the Bell Labs vulnerability.
wu-ftpd 2.4 FTP server does not properly drop privileges when an ABOR (abort file transfer) command is executed during a file transfer, which causes a signal to be handled incorrectly and allows local and possibly remote attackers to read arbitrary files.
Denial of service in RPC portmapper allows attackers to register or unregister RPC services or spoof RPC services using a spoofed source IP address such as 127.0.0.1.
ping in Solaris 2.3 through 2.6 allows local users to cause a denial of service (crash) via a ping request to a multicast address through the loopback interface, e.g. via ping -i.
rsh daemon (rshd) generates different error messages when a valid username is provided versus an invalid name, which allows remote attackers to determine valid users on the system.
