POP3Lite before 0.2.4 does not properly quote a . (dot) in an email message, which could allow a remote attacker to append arbitrary text to the end of an email message, which could then be interpreted by various mail clients as valid POP server responses or other input that could cause clients to crash or otherwise behave unexpectedly.

keyinit in S/Key does not require authentication to initialize a one-time password sequence, which allows an attacker who has gained privileges to a user account to create new one-time passwords for use in other activities that may use S/Key authentication, such as sudo.

imwheel-solo in imwheel package allows local users to modify arbitrary files via a symlink attack from the .imwheelrc file.

htsearch program in htDig 3.2 beta, 3.1.6, 3.1.5, and earlier allows remote attackers to determine the physical path of the server by requesting a non-existent configuration file using the config parameter, which generates an error message that includes the full path.

Buffer overflow in BTT Software SNMP Trap Watcher 1.16 allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, via a long string trap.

Performance Metrics Collector Daemon (PMCD) in Performance Copilot in IRIX 6.x allows remote attackers to cause a denial of service (resource exhaustion) via an extremely long string to the PMCD port.

Argosoft FRP server 1.0 allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, via a long string to the (1) USER or (2) CWD commands.

telnet daemon (telnetd) from the Linux netkit package before netkit-telnet-0.16 allows remote attackers to bypass authentication when telnetd is running with the -L command line option.

PSCOErrPage.htm in Netscape PublishingXpert 2.5 before SP2 allows remote attackers to read arbitrary files by specifying the target file in the errPagePath parameter.

POP2 or POP3 server (pop3d) in imap-uw IMAP package on FreeBSD and other operating systems creates lock files with predictable names, which allows local users to cause a denial of service (lack of mail access) for other users by creating lock files for other mail boxes.

qpopper POP server creates lock files with predictable names, which allows local users to cause a denial of service for other users (lack of mail access) by creating lock files for other mail boxes.

PostgreSQL stores usernames and passwords in plaintext in (1) pg_shadow and (2) pg_pwd, which allows attackers with sufficient privileges to gain access to databases.

Windows NT allows remote attackers to list all users in a domain by obtaining the domain SID with the LsaQueryInformationPolicy policy function via a null session and using the SID to list the users.

Check Point FireWall-1 allows remote attackers to cause a denial of service (high CPU) via a flood of packets to port 264.

ikeyman in IBM IBMHSSSB 1.0 sets the CLASSPATH environmental variable to include the user's own CLASSPATH directories before the system's directories, which allows a malicious local user to execute arbitrary code as root via a Trojan horse Ikeyman class.

Cisco IOS 11.x and 12.0 with ATM support allows attackers to cause a denial of service via the undocumented Interim Local Management Interface (ILMI) SNMP community string.

dbsnmp in Oracle 8.0.5 and 8.1.5, under certain conditions, trusts the PATH environment variable to find and execute the (1) chown or (2) chgrp commands, which allows local users to execute arbitrary code by modifying the PATH to point to Trojan Horse programs.

glFTPD 1.23 allows remote attackers to cause a denial of service (CPU consumption) via a LIST command with an argument that contains a large number of * (asterisk) characters.

Directory traversal vulnerability in Nudester 1.10 and earlier allows remote attackers to read or write arbitrary files via a .. (dot dot) in the CD (CWD) command.

Knox Arkeia server 4.2, and possibly other versions, uses a constant salt when encrypting passwords using the crypt() function, which makes it easier for an attacker to conduct brute force password guessing.
