Debian DSA-117-1 : cvs - improper variable initialization

Kim Nielsen recently found an internal problem with the CVS server and reported it to the vuln-dev mailing list. The problem is triggered by an improperly initialized global variable. A user exploiting this can crash the CVS server, which may be accessed through the pserver service and running...

Debian DSA-459-1 : kdelibs - cookie path traversal

A vulnerability was discovered in KDE where the path restrictions on cookies could be bypassed using encoded relative path components e.g., '/../'. This means that a cookie which should only be sent by the browser to an application running at /app1, the browser could inadvertently include it with...

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-471-1 : interchange - missing input sanitising

A vulnerability was discovered recently in Interchange, an e-commerce and general HTTP database display system. This vulnerability can be exploited by an attacker to expose the content of arbitrary variables. An attacker may learn SQL access information for your Interchange application and use th...

Debian DSA-123-1 : listar - remote exploit

Janusz Niewiadomski and Wojciech Purczynski reported a buffer overflow in the addressmatch of listar a listserv style mailing-list manager. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from Debian Security Advisory...

Debian DSA-309-1 : eterm - buffer overflow

'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. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package...

Debian DSA-376-2 : exim - buffer overflow

A buffer overflow exists in exim, which is the standard mail transport agent in Debian. By supplying a specially crafted HELO or EHLO command, an attacker could cause a constant string to be written past the end of a buffer allocated on the heap. This vulnerability is not believed at this time to...

Debian DSA-017-1 : jazip - buffer overflow

With older versions of jazip a user could gain root access for members of the floppy group to the local machine. The interface doesn't run as root anymore and this very exploit was prevented. The program now also truncates DISPLAY to 256 characters if it is bigger, which closes the buffer overflo...

Debian DSA-021-1 : apache - insecure tempfile bug, broken mod_rewrite

WireX have found some occurrences of insecure opening of temporary files in htdigest and htpasswd. Both programs are not installed setuid or setgid and thus the impact should be minimal. The Apache group has released another security bugfix which fixes a vulnerability in modrewrite which may resu...

Debian DSA-177-1 : pam -- serious security violation

A serious security violation in PAM was discovered. Disabled passwords i.e. those with '' in the password file were classified as empty password and access to such accounts is granted through the regular login procedure getty, telnet, ssh. This works for all such accounts whose shell field in the...

Debian DSA-258-1 : ethereal - format string vulnerability

Georgi Guninski discovered a problem in ethereal, a network traffic analyzer. The program contains a format string vulnerability that could probably lead to execution of arbitrary code. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin wer...

Debian DSA-414-1 : jabber - denial of service

A vulnerability was discovered in jabber, an instant messaging server, whereby a bug in the handling of SSL connections could cause the server process to crash, resulting in a denial of service. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this...

Debian DSA-455-1 : libxml - buffer overflows

libxml2 is a library for manipulating XML files. Yuuichi Teranishi Si Xi Yu ? discovered a flaw in libxml, the GNOME XML library. When fetching a remote resource via FTP or HTTP, the library uses special parsing routines which can overflow a buffer if passed a very long URL. If an attacker is abl...

Debian DSA-247-1 : courier-ssl - missing input sanitizing

The developers of courier, an integrated user side mail server, discovered a problem in the PostgreSQL auth module. Not all potentially malicious characters were sanitized before the username was passed to the PostgreSQL engine. An attacker could inject arbitrary SQL commands and queries exploiti...

Debian DSA-501-1 : exim - buffer overflow

Georgi Guninski discovered two stack-based buffer overflows. They can not be exploited with the default configuration from the Debian system, though. The Common Vulnerabilities and Exposures project identifies the following problems that are fixed with this update : - CAN-2004-0399 When...

Debian DSA-207-1 : tetex-bin - arbitrary command execution

The SuSE security team discovered a vulnerability in kpathsea library libkpathsea which is used by xdvi and dvips. Both programs call the system function insecurely, which allows a remote attacker to execute arbitrary commands via cleverly crafted DVI files. If dvips is used in a print filter, th...

Debian DSA-344-2 : unzip - directory traversal

A directory traversal vulnerability in UnZip 5.50 allows attackers to bypass a check for relative pathnames '../' by placing certain invalid characters between the two '.' characters. The fix which was implemented in DSA-344-1 may not have protected against all methods of exploiting this...

Debian DSA-333-1 : acm - integer overflow

acm, a multi-player aerial combat simulation, uses a network protocol based on the same RPC implementation used in many C libraries. This implementation was found to contain an integer overflow vulnerability which could be exploited to execute arbitrary code. %NASLMINLEVEL 70300 C Tenable Network...

Debian DSA-429-1 : gnupg - cryptographic weakness

Phong Nguyen identified a severe bug in the way GnuPG creates and uses ElGamal keys for signing. This is a significant security failure which can lead to a compromise of almost all ElGamal keys used for signing. This update disables the use of this type of key. %NASLMINLEVEL 70300 C Tenable Netwo...
