Buffer overflow in ncurses 5.0, and the ncurses4 compatibility package as used in Red Hat Linux, allows local users to gain privileges, related to "routines for moving the physical cursor and scrolling."
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.
Linux gpm program allows local users to cause a denial of service by flooding the /dev/gpmctl device with STREAM sockets.
rpc.lockd in Red Hat Linux 6.1 and 6.2 allows remote attackers to cause a denial of service via a malformed request.
The pamconsole 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.
ORBit and gnome-session in Red Hat Linux 6.1 allows remote attackers to crash a program.
ORBit and esound in Red Hat Linux 6.1 do not use sufficiently random numbers, which allows local users to guess the authentication keys.
Pluggable Authentication Modules (PAM) in Red Hat Linux 6.1 does not properly lock access to disabled NIS accounts.
Linux OpenLDAP server allows local users to modify arbitrary files via a symlink attack.
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.
X fontserver xfs allows local users to cause a denial of service via malformed input to the server.
The X font server xfs in Red Hat Linux 6.x allows an attacker to cause a denial of service via a malformed request.
Buffer overflow in imwheel allows local users to gain root privileges via the imwheel-solo script and a long HOME environmental variable.
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 mhshow in the Linux nmh package allows remote attackers to execute commands via malformed MIME headers in an email message.
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.
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.
An installation of Red Hat uses DES password encryption with crypt() for the initial password, instead of md5.
Red Hat userhelper program in the usermode package allows local users to gain root access via PAM and a .. (dot dot) attack.
PAM configuration file for rlogin in Red Hat Linux 6.1 and earlier includes a less restrictive rule before a more restrictive one, which allows users to access the host via rlogin even if rlogin has been explicitly disabled using the /etc/nologin file.
Xsession in Red Hat Linux 6.1 and earlier can allow local users with restricted accounts to bypass execution of the .xsession file by starting kde, gnome or anotherlevel from kdm.
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 pamlocaluser PAM module in Red Hat Linux 7.x and 6.x allows attackers 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.
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.
The tmpwatch utility in Red Hat Linux forks a new process for each directory level, which allows local users to cause a denial of service by creating deeply nested directories in /tmp or /var/tmp/.
mopd (Maintenance Operations Protocol loader daemon) does not properly cleanse user-injected format strings, which allows remote attackers to execute arbitrary commands.
Buffer overflow in mopd (Maintenance Operations Protocol loader daemon) allows remote attackers to execute arbitrary commands via a long file name.
