rmuser utility in FreeBSD 4.2 and 4.3 creates a copy of the master.passwd file with world-readable permissions while updating the original file, which could allow local users to gain privileges by reading the copied file while rmuser is running, obtain the password hashes, and crack the passwords.

Buffer overflow in the (1) smap/smapd and (2) CSMAP daemons for Gauntlet Firewall 5.0 through 6.0 allows remote attackers to execute arbitrary code via a crafted mail message.

login in HP-UX 10.26 does not record failed login attempts in /var/adm/btmp, which could allow attackers to conduct brute force password guessing attacks without being detected or observed using the lastb program.

Buffer overflow in swverify in HP-UX 11.0, and possibly other programs, allows local users to gain privileges via a long command line argument.

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.
