Debian DSA-273-1 : krb4 - Cryptographic weakness

A cryptographic weakness in version 4 of the Kerberos protocol allows an attacker to use a chosen-plaintext attack to impersonate any principal in a realm. Additional cryptographic weaknesses in the krb4 implementation permit the use of cut-and-paste attacks to fabricate krb4 tickets for...

Debian DSA-505-1 : cvs - heap overflow

Stefan Esser discovered a heap overflow in the CVS server, which serves the popular Concurrent Versions System. Malformed 'Entry' Lines in combination with Is-modified and Unchanged can be used to overflow malloced memory. This was proven to be exploitable. %NASLMINLEVEL 70300 C Tenable Network...

Debian DSA-095-1 : gpm - local root vulnerability

The package 'gpm' contains the gpm-root program, which can be used to create mouse-activated menus on the console. Among other problems, the gpm-root program contains a format string vulnerability, which allows an attacker to gain root privileges. %NASLMINLEVEL 70300 C Tenable Network Security,...

Debian DSA-457-1 : wu-ftpd - several vulnerabilities

Two vulnerabilities were discovered in wu-ftpd : - CAN-2004-0148 Glenn Stewart discovered that users could bypass the directory access restrictions imposed by the restricted-gid option by changing the permissions on their home directory. On a subsequent login, when access to the user's home...

Debian DSA-200-1 : samba - remote exploit

Steve Langasek found an exploitable bug in the password handling code in samba: when converting from DOS code-page to little endian UCS2 unicode a buffer length was not checked and a buffer could be overflowed. There is no known exploit for this, but an upgrade is strongly recommended...

Debian DSA-049-1 : cfingerd

Megyer Laszlo report on Bugtraq that the cfingerd daemon as distributed with Debian GNU/Linux 2.2 was not careful in its logging code. By combining this with an off-by-one error in the code that copied the username from an ident response cfingerd could be exploited by a remote user. Since cfinger...

Debian DSA-349-1 : nfs-utils - buffer overflow

The logging code in nfs-utils contains an off-by-one buffer overrun when adding a newline to the string being logged. This vulnerability may allow an attacker to execute arbitrary code or cause a denial of service condition by sending certain RPC requests. %NASLMINLEVEL 70300 C Tenable Network...

Debian DSA-426-1 : netpbm-free - insecure temporary files

netpbm is a graphics conversion toolkit made up of a large number of single-purpose programs. Many of these programs were found to create temporary files in an insecure manner, which could allow a local attacker to overwrite files with the privileges of the user invoking a vulnerable netpbm tool...

Debian DSA-314-1 : atftp - buffer overflow

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. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in thi...

Debian DSA-213-1 : libpng - buffer overflow

Glenn Randers-Pehrson discovered a problem in connection with 16-bit samples from libpng, an interface for reading and writing PNG Portable Network Graphics format files. The starting offsets for the loops are calculated incorrectly which causes a buffer overrun beyond the beginning of the row...

Debian DSA-444-1 : linux-kernel-2.4.17-ia64 - missing function return value check

Paul Starzetz and Wojciech Purczynski of isec.pl discovered a critical security vulnerability in the memory management code of Linux inside the mremap2 system call. Due to missing function return value check of internal functions a local attacker can gain root privileges. %NASLMINLEVEL 70300 C...

Debian DSA-541-1 : icecast-server - missing escape

Markus Worle discovered a cross site scripting problem in status-display list.cgi of the icecast internal webserver, an MPEG layer III streaming server. The UserAgent variable is not properly htmlescaped so that an attacker could cause the client to execute arbitrary Java script commands...

Debian DSA-281-1 : moxftp - buffer overflow

Knud Erik Hojgaard discovered a vulnerability in moxftp and xftp respectively, an Athena X interface to FTP. Insufficient bounds checking could lead to execution of arbitrary code, provided by a malicious FTP server. Erik Tews fixed this. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The...

Debian DSA-511-1 : ethereal - buffer overflows

Several buffer overflow vulnerabilities were discovered in ethereal, a network traffic analyzer. These vulnerabilities are described in the ethereal advisory 'enpa-sa-00013'. Of these, only some parts of CAN-2004-0176 affect the version of ethereal in Debian woody. CAN-2004-0367 and CAN-2004-0365...

Debian DSA-387-1 : gopher - buffer overflows

gopherd, a gopher server from the University of Minnesota, contains a number of buffer overflows which could be exploited by a remote attacker to execute arbitrary code with the privileges of the gopherd process the 'gopher' user by default. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. Th...

Debian DSA-186-1 : log2mail - buffer overflow

Enrico Zini discovered a buffer overflow in log2mail, a daemon for watching logfiles and sending lines with matching patterns via mail. The log2mail daemon is started upon system boot and runs as root. A specially crafted remote log message could overflow a static buffer, potentially leaving...

Debian DSA-176-1 : gv - buffer overflow

Zen-parse discovered a buffer overflow in gv, a PostScript and PDF viewer for X11. This problem is triggered by scanning the PostScript file and can be exploited by an attacker sending a malformed PostScript or PDF file. The attacker is able to cause arbitrary code to be run with the privileges o...

Debian DSA-189-1 : luxman - local root exploit

iDEFENSE reported about a vulnerability in LuxMan, a maze game for GNU/Linux, similar to the PacMan arcade game. When successfully exploited a local attacker gains read-write access to the memory, leading to a local root compromise in many ways, examples of which include scanning the file for...

Debian DSA-180-1 : nis - information leak

Thorsten Kukuck discovered a problem in the ypserv program which is part of the Network Information Services NIS. A memory leak in all versions of ypserv prior to 2.5 is remotely exploitable. When a malicious user could request a non-existing map the server will leak parts of an old domainname an...

Debian DSA-375-1 : node - buffer overflow, format string

Morgan alias SM6TKY discovered and fixed several security related problems in LinuxNode, an Amateur Packet Radio Node program. The buffer overflow he discovered can be used to gain unauthorised root access and can be remotely triggered. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The...
