userhelper in the usermode package on Red Hat Linux executes non-setuid programs as root, which does not activate the security measures in glibc and allows the programs to be exploited via format string vulnerabilities in glibc via the LANG or LC_ALL environment variables (CVE-2000-0844).

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.

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

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

Red Hat Linux screen program does not use Unix98 ptys, allowing local users to write to other terminals.

Buffer overflow in Linux linuxconf package allows remote attackers to gain root privileges via a long parameter.

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.

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.

Buffer overflow in bootpd on OpenBSD, FreeBSD, and Linux systems via a malformed header type.

Samba 1.9.18 inadvertently includes a prototype application, wsmbconf, which is installed with incorrect permissions including the setgid bit, which allows local users to read and write files and possibly gain privileges via bugs in the program.

Arbitrary command execution via metamail package using message headers, when user processes attacker's message using metamail.

Buffer overflow in Vixie Cron library up to version 3.0 allows local users to obtain root access via a long environmental variable.

rpc.lockd in Red Hat Linux 6.1 and 6.2 allows remote attackers to cause a denial of service via a malformed request.
