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

The pam_console PAM module in Linux systems performs a chown on various devices upon a user login, but an open file descriptor for those devices can be maintained after the user logs out, which allows that user to sniff activity on these devices when subsequent users log in.

Linux OpenLDAP server allows local users to modify arbitrary files via a symlink attack.

The X font server xfs in Red Hat Linux 6.x allows an attacker to cause a denial of service via a malformed request.

X fontserver xfs allows local users to cause a denial of service via malformed input to the server.

IP masquerading in Linux 2.2.x allows remote attackers to route UDP packets through the internal interface by modifying the external source IP address and port number to match those of an established connection.

gpm-root in the gpm package does not properly drop privileges, which allows local users to gain privileges by starting a utility from gpm-root.

Buffer overflow in imwheel allows local users to gain root privileges via the imwheel-solo script and a long HOME environmental variable.

Linux printtool sets the permissions of printer configuration files to be world-readable, which allows local attackers to obtain printer share passwords.

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

An installation of Red Hat uses DES password encryption with crypt() for the initial password, instead of md5.

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.

Red Hat userhelper program in the usermode package allows local users to gain root access via PAM and a .. (dot dot) attack.

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.

ORBit and esound in Red Hat Linux 6.1 do not use sufficiently random numbers, which allows local users to guess the authentication keys.

ORBit and gnome-session in Red Hat Linux 6.1 allows remote attackers to crash a program.
