ZoneAlarm and ZoneAlarm Pro allows a local attacker to cause a denial of service by running a trojan to initialize a ZoneAlarm mutex object which prevents ZoneAlarm from starting.

Webridge PX Application Suite allows remote attackers to obtain sensitive information via a malformed request that generates a server error message, which includes full pathname or internal IP address information in the variables (1) APPL_PHYSICAL_PATH, (2) PATH_TRANSLATED, and (3) LOCAL_ADDR.

Apache with mod_rewrite enabled on most UNIX systems allows remote attackers to bypass RewriteRules by inserting extra / (slash) characters into the requested path, which causes the regular expression in the RewriteRule to fail.

qpopper 4.01 with PAM based authentication on Red Hat systems generates different error messages when an invalid username is provided instead of a valid name, which allows remote attackers to determine valid usernames on the system.

Web-based configuration utility in Cisco 600 series routers running CBOS 2.0.1 through 2.4.2ap binds itself to port 80 even when web-based configuration services are disabled, which could leave the router open to attack.

Cisco 600 series routers running CBOS 2.0.1 through 2.4.2ap allows remote attackers to cause a denial of service via multiple connections to the router on the (1) HTTP or (2) telnet service, which causes the router to become unresponsive and stop forwarding packets.

Starfish Truesync Desktop 2.0b as used on the REX 5000 PDA uses a small keyspace for device keys and does not impose a delay when an incorrect key is entered, which allows attackers to more quickly guess the key via a brute force attack.

Starfish Truesync Desktop 2.0b as used on the REX 5000 PDA does not encrypt sensitive files and relies solely on its password feature to restrict access, which allows an attacker to read the files using a different application.
