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.

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.

Format string vulnerability in talkd in OpenBSD and possibly other BSD-based OSes allows remote attackers to execute arbitrary commands via a user name that contains format characters.

Some functions that implement the locale subsystem on Unix do not properly cleanse user-injected format strings, which allows local attackers to execute arbitrary commands via functions such as gettext and catopen.

Buffer overflow in NFS server on Linux allows attackers to execute commands via a long pathname.

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

Buffer overflow in Berkeley automounter daemon (amd) logging facility provided in the Linux am-utils package and others.

Format string vulnerability in Mutt before 1.2.5 allows a remote malicious IMAP server to execute arbitrary commands.

Buffer overflow in mhshow in the Linux nmh package allows remote attackers to execute commands via malformed MIME headers in an email message.

wu-ftp with FTP conversion enabled allows an attacker to execute commands via a malformed file name that is interpreted as an argument to the program that does the conversion, e.g. tar or uncompress.

Buffer overflow in Vixie Cron on Red Hat systems via the MAILTO environmental variable.

The Squid package in Red Hat Linux 5.2 and 6.0, and other distributions, installs cachemgr.cgi in a public web directory, which allows remote attackers to use it as an intermediary to connect to other systems.

Linux xmonisdn package allows local users to gain root privileges by modifying the IFS or PATH environmental variables.

Buffer overflow in ultimatesource function of man 1.5 and earlier allows local users to gain privileges.

Multiple shell programs on various Unix systems, including (1) tcsh, (2) csh, (3) sh, and (4) bash, follow symlinks when processing << redirects (aka here-documents or in-here documents), which allows local users to overwrite files of other users via a symlink attack.

Glint in Red Hat Linux 5.2 allows local users to overwrite arbitrary files and cause a denial of service via a symlink attack.

Kernel logging daemon (klogd) in Linux does not properly cleanse user-injected format strings, which allows local users to gain root privileges by triggering malformed kernel messages.

Buffer overflow in fld program in Kanji on Console (KON) package on Linux may allow local users to gain root privileges via an input file containing long CHARSETREGISTRY or CHARSETENCODING settings.

makewhatis in Linux man package allows local users to overwrite files via a symlink attack.

Buffer overflow in kon program in Kanji on Console (KON) package on Linux may allow local users to gain root privileges via a long -StartupMessage parameter.

Buffer overflow in the dump utility in the Linux ext2fs backup package allows local users to gain privileges via a long command line argument.

Buffer overflow in the man program in Linux allows local users to gain privileges via the MANPAGER environmental variable.

The Red Hat Linux su program does not log failed password guesses if the su process is killed before it times out, which allows local attackers to conduct brute force password guessing.

Buffer overflow in Vixie cron allows local users to gain root access via a long MAILTO environment variable in a crontab file.

Vixie Cron on Linux systems allows local users to set parameters of sendmail commands via the MAILTO environmental variable.

A buffer overflow in lsof allows local users to obtain root privilege.

Buffer overflow in Dosemu Slang library in Linux.

Remote attackers can cause a denial of service on Linux in.telnetd telnet daemon through a malformed TERM environmental variable.

The ping command in Linux 2.0.3x allows local users to cause a denial of service by sending large packets with the -R (record route) option.

Buffer overflow in man program in various distributions of Linux allows local user to execute arbitrary code as group man via a long -S option.
