radiusd-cistron contains a bug allowing a buffer overflow when a long NAS-Port attribute is received. This could allow a remote attacker to execute arbitrary code on the with the privileges of the RADIUS daemon (usually root).

Ingo Saitz discovered a bug in mikmod whereby a long filename inside an archive file can overflow a buffer when the archive is being read by mikmod.

The package radiusd-cistron is an implementation of the RADIUS protocol. Unfortunately the RADIUS server handles too large NAS numbers not correctly. This leads to overwriting internal memory of the server process and may be abused to gain remote access to the system the RADIUS server is running on.

miniserv.pl in the webmin package does not properly handle metacharacters, such as line feeds and carriage returns, in Base64-encoded strings used in Basic authentication. This vulnerability allows remote attackers to spoof a session ID, and thereby gain root privileges.

Calle Dybedahl discovered a bug in lyskom-server which could result in a denial of service where an unauthenticated user could cause the server to become unresponsive as it processes a large query.

The CUPS print server in Debian is vulnerable to a denial of service when an HTTP request is received without being properly terminated.

The slashem package is vulnerable to a buffer overflow exploited via a long '-s' command line option. This vulnerability could be used by an attacker to gain gid 'games' on a system where slashem is installed.

The nethack package is vulnerable to a buffer overflow exploited via a long '-s' command line option. This vulnerability could be used by an attacker to gain gid 'games' on a system where nethack is installed.

Bas Wijnen discovered that the gnocatan server is vulnerable to several buffer overflows which could be exploited to execute arbitrary code on the server system

Rick Patel discovered that atftpd is vulnerable to a buffer overflow when a long filename is sent to the server. An attacker could exploit this bug remotely to execute arbitrary code on the server.

Timo Sirainen discovered several vulnerabilities in ethereal, a network traffic analyzer. These include one-byte buffer overflows in the AIM, GIOP Gryphon, OSPF, PPTP, Quake, Quake2, Quake3, Rsync, SMB, SMPP, and TSP dissectors, and integer overflows in the Mount and PPP dissectors.

A buffer overflow was fixed in DSA-309-1, but a different error was introduced in the handling of the ETERMPATH environment variable. This bug was not security-related, but would cause this environment variable not to be recognized correctly. This is now corrected by an updated version of the package.

Multiple vulnerabilities were discovered and fixed in the Linux kernel.

A vulnerability was discovered in Ghostscript versions prior to 7.07 that allowed malicious postscript files to execute arbitrary commands even when -dSAFER is enabled.

A number of vulnerabilities have been discovered in the Linux kernel.

XaoS, a program for displaying fractal images, is installed setuid root on certain architectures in order to use svgalib, which requires access to the video hardware. However, it is not designed for secure setuid execution, and can be exploited to gain root privileges.

A number of vulnerabilities have been discovered in the Linux kernel.

"bazarr" discovered that eterm is vulnerable to a buffer overflow of the ETERMPATH environment variable. This bug can be exploited to gain the privileges of the group "utmp" on a system where eterm is installed.

Paul Szabo discovered that znew, a script included in the gzip package, creates its temporary files without taking precautions to avoid a symlink attack (CAN-2003-0367).

The PPTP daemon contains a remotely exploitable buffer overflow which was introduced due to a integer overflow in the third argument passed to the read() library call. This bug has been fixed. Since there is no workaround other than shutting down the PPTP daemon an update is strongly recommended if you need a PPTP server running.
