ssh 2.0.12, and possibly other versions, allows valid user names to attempt to enter the correct password multiple times, but only prompts an invalid user name for a password once, which allows remote attackers to determine user account names on the server.

The Red Hat Linux su program does not log failed password guesses if the su process is killed before it times out, which allows local attackers to conduct brute force password guessing.

Sudo 1.5 in Debian Linux 2.1 and Red Hat 6.0 allows local users to determine the existence of arbitrary files by attempting to execute the target filename as a program, which generates a different error message when the file does not exist.

rpc.statd allows remote attackers to forward RPC calls to the local operating system via the SM_MON and SM_NOTIFY commands, which in turn could be used to remotely exploit other bugs such as in automountd.

Multiple buffer overflows in smbvalid/smbval SMB authentication library, as used in Apache::AuthenSmb and possibly other modules, allows remote attackers to execute arbitrary commands via (1) a long username, (2) a long password, and (3) other unspecified methods.

The OmniHTTPD visadmin.exe program allows a remote attacker to conduct a denial of service via a malformed URL which causes a large number of temporary files to be created.

The Economist screen saver 1999 with the "Password Protected" option enabled allows users with physical access to the machine to bypass the screen saver and read files by running Internet Explorer while the screen is still locked.

A possible interaction between Apple MacOS X release 1.0 and Apache HTTP server allows remote attackers to cause a denial of service (crash) via a flood of HTTP GET requests to CGI programs, which generates a large number of processes.

Denial of service in Compaq Management Agents and the Compaq Survey Utility via a long string sent to port 2301.

Denial of service in Linux 2.2.x kernels via malformed ICMP packets containing unusual types, codes, and IP header lengths.

CDomain whois_raw.cgi whois CGI script allows remote attackers to execute arbitrary commands via shell metacharacters in the fqdn parameter.

screen and rxvt in Red Hat Linux 6.0 do not properly set the modes of tty devices, which allows local users to write to other ttys.

Red Hat Linux 6.0 installs the /dev/pts file system with insecure modes, which allows local users to write to other tty devices.

Vulnerabilities in the KDE kvt terminal program allow local users to gain root privileges.

Buffer overflow in KDE Kmail allows a remote attacker to cause a denial of service via an attachment with a long file name.

nsd in IRIX 6.5 through 6.5.2 exports a virtual filesystem on a UDP port, which allows remote attackers to view files and cause a possible denial of service by mounting the nsd virtual file system.

tcpdump, Ethereal, and other sniffer packages allow remote attackers to cause a denial of service via malformed DNS packets in which a jump offset refers to itself, which causes tcpdump to enter an infinite loop while decompressing the packet.

Symantec pcAnywhere 8.0 allows remote attackers to cause a denial of service (CPU utilization) via a large amount of data to port 5631.

Windows NT RRAS and RAS clients cache a user's password even if the user has not selected the "Save password" option.

Buffer overflow in Internet Explorer 5 allows remote attackers to execute commands via a malformed Favorites icon.
