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-215-1 : cyrus-imapd - buffer overflow

Timo Sirainen discovered a buffer overflow in the Cyrus IMAP server, which could be exploited by a remote attacker prior to logging in. A malicious user could craft a request to run commands on the server under the UID and GID of the cyrus server. %NASLMINLEVEL 70300 C Tenable Network Security,...

Debian DSA-526-1 : webmin - several vulnerabilities

Two vulnerabilities were discovered in webmin : CAN-2004-0582: Unknown vulnerability in Webmin 1.140 allows remote attackers to bypass access control rules and gain read access to configuration information for a module. CAN-2004-0583: The account lockout functionality in 1 Webmin 1.140 and 2...

Debian DSA-522-1 : super - format string vulnerability

Max Vozeler discovered a format string vulnerability in super, a program to allow specified users to execute commands with root privileges. This vulnerability could potentially be exploited by a local user to execute arbitrary code with root privileges. %NASLMINLEVEL 70300 C Tenable Network...

Debian DSA-313-1 : ethereal - buffer overflows, integer overflows

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. %NASLMINLEVEL...

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-233-1 : cvs - doubly freed memory

Stefan Esser discovered a problem in cvs, a concurrent versions system, which is used for many Free Software projects. The current version contains a flaw that can be used by a remote attacker to execute arbitrary code on the CVS server under the user id the CVS server runs as. Anonymous read-onl...

Debian DSA-285-1 : lprng - insecure temporary file

Karol Lewandowski discovered that psbanner, a printer filter that creates a PostScript format banner and is part of LPRng, insecurely creates a temporary file for debugging purpose when it is configured as filter. The program does not check whether this file already exists or is linked to another...

Debian DSA-252-1 : slocate - buffer overflow

A problem has been discovered in slocate, a secure locate replacement. A buffer overflow in the setgid program slocate can be used to execute arbitrary code as group slocate. This can be used to alter the slocate database. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text...

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-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-253-1 : openssl - information leak

A vulnerability has been discovered in OpenSSL, a Secure Socket Layer SSL implementation. In an upcoming paper, Brice Canvel EPFL, Alain Hiltgen UBS, Serge Vaudenay EPFL, and Martin Vuagnoux EPFL, Ilion describe and demonstrate a timing-based attack on CBC cipher suites used in SSL and TLS. OpenS...

Debian DSA-284-1 : kdegraphics - insecure execution

The KDE team discovered a vulnerability in the way KDE uses Ghostscript software for processing of PostScript PS and PDF files. An attacker could provide a malicious PostScript or PDF file via mail or websites that could lead to executing arbitrary commands under the privileges of the user viewin...

Debian DSA-263-1 : netpbm-free - math overflow errors

Al Viro and Alan Cox discovered several maths overflow errors in NetPBM, a set of graphics conversion tools. These programs are not installed setuid root but are often installed to prepare data for processing. These vulnerabilities may allow remote attackers to cause a denial of service or execut...

Debian DSA-047-1 : kernel
