login in Slackware Linux 3.2 through 3.5 does not properly check for an error when the /etc/group file is missing, which prevents it from dropping privileges, causing it to assign root privileges to any local user who logs on to the server.

A default configuration of in.identd in SuSE Linux waits 120 seconds between requests, allowing a remote attacker to conduct a denial of service.

Buffer overflow in telnet daemon tgetent routing allows remote attackers to gain root access via the TERMCAP environmental variable.
