Red Hat Linux 4.2

Inverse query buffer overflow in BIND 4.9 and BIND 8 Releases.

Buffer overflow in NFS mountd gives root access to remote attackers, mostly in Linux systems.

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.

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

Denial of Service vulnerabilities in BIND 4.9 and BIND 8 Releases via CNAME record and zone transfer.

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

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

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

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

Buffer overflow in suidperl (sperl), Perl 4.x and 5.x.

Vixie Cron on Linux systems allows local users to set parameters of sendmail commands via the MAILTO 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 Dosemu Slang library in Linux.

Buffer overflow in run-time linkers (1) ld.so or (2) ld-linux.so for Linux systems allows local users to gain privileges by calling a setuid program with a long program name (argv[0]) and forcing ld.so/ld-linux.so to report an error.

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

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

Denial of Service vulnerability in BIND 8 Releases via maliciously formatted DNS messages.

Buffer overflow in SGI IRIX mailx program.

Buffer overflow in bash 2.0.0, 1.4.17, and other versions allows local attackers to gain privileges by creating an extremely large directory name, which is inserted into the password prompt via the \w option in the PS1 environmental variable when another user changes into that directory.

The snprintf function in the db library 1.85.4 ignores the size parameter, which could allow attackers to exploit buffer overflows that would be prevented by a properly implemented snprintf.

netcfg 2.16-1 in Red Hat Linux 4.2 allows the Ethernet interface to be controlled by users on reboot when an option is set, which allows local users to cause a denial of service by shutting down the interface.
