inpview in InPerson in SGI IRIX 5.3 through IRIX 6.5.10 allows local users to gain privileges via a symlink attack on the .ilmpAAA temporary file.

Telnetd telnet server in IRIX 5.2 through 6.1 does not properly cleans user-injected format strings, which allows remote attackers to execute arbitrary commands via a long RLD variable in the IAC-SB-TELOPT_ENVIRON request.

The line printer daemon (lpd) in the lpr package in multiple Linux operating systems allows local users to gain root privileges by causing sendmail to execute with arbitrary command line arguments, as demonstrated using the -C option to specify a configuration file.

The line printer daemon (lpd) in the lpr package in multiple Linux operating systems authenticates by comparing the reverse-resolved hostname of the local machine to the hostname of the print server as returned by gethostname, which allows remote attackers to bypass intended access controls by modifying the DNS for the attacking IP.
