Debian DSA-092-1 : wmtv - local root exploit

Nicolas Boullis found a nasty security problem in the wmtv a dockable video4linux TV player for windowmaker package as distributed in Debian GNU/Linux 2.2. wmtv can optionally run a command if you double-click on the TV window. This command can be specified using the -e command line option...

Debian DSA-353-1 : sup - insecure temporary file

sup, a package used to maintain collections of files in identical versions across machines, fails to take appropriate security precautions when creating temporary files. A local attacker could exploit this vulnerability to overwrite arbitrary files with the privileges of the user running sup...

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-048-3 : samba

Marcus Meissner discovered that samba was not creating temporary files safely in two places : - when a remote user queried a printer queue samba would create a temporary file in which the queue data would be written. This was being done using a predictable filename, and insecurely, allowing a loc...

Debian DSA-098-1 : libgtop - format string vulnerability and buffer overflow

Two different problems were found in libgtop-daemon : - The laboratory intexxia found a format string problem in the logging code from libgtopdaemon. There were two logging functions which are called when authorizing a client which could be exploited by a remote user. - Flavio Veloso found a buff...

Debian DSA-335-1 : mantis - incorrect permissions

mantis, a PHP/MySQL web-based bug tracking system, stores the password used to access its database in a configuration file which is world-readable. This could allow a local attacker to read the password and gain read/write access to the database. %NASLMINLEVEL 70300 C Tenable Network Security, In...

Debian DSA-103-1 : glibc - buffer overflow

A buffer overflow has been found in the globbing code for glibc. This is the code which is used to glob patterns for filenames and is commonly used in applications like shells and FTP servers. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this...

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-136-1 : openssl - multiple remote exploits

The OpenSSL development team has announced that a security audit by A.L. Digital Ltd and The Bunker, under the DARPA CHATS program, has revealed remotely exploitable buffer overflow conditions in the OpenSSL code. Additionally, the ASN1 parser in OpenSSL has a potential DoS attack independently...

Debian DSA-259-1 : qpopper - mail user privilege escalation

Florian Heinz posted to the Bugtraq mailing list an exploit for qpopper based on a bug in the included vsnprintf implementation. The sample exploit requires a valid user account and password, and overflows a string in the popmsg function to give the user 'mail' group privileges and a shell on the...

Debian DSA-101-1 : sudo - Local root exploit

Sebastian Krahmer from SuSE found a vulnerability in sudo which could easily lead into a local root exploit. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from Debian Security Advisory DSA-101. The text itself is copyrig...

Debian DSA-039-1 : glibc

The version of GNU libc that was distributed with Debian GNU/Linux 2.2 suffered from 2 security problems : - It was possible to use LDPRELOAD to load libraries that are listed in /etc/ld.so.cache, even for suid programs. This could be used to create and overwrite files which a user should not be...

Debian DSA-032-1 : proftpd - proftpd running with incorrect userid, erroneous file removal

The following problems have been reported for the version of proftpd in Debian 2.2 potato : - There is a configuration error in the postinst script, when the user enters 'yes', when asked if anonymous access should be enabled. The postinst script wrongly leaves the 'run as uid/gid root'...

Debian DSA-378-1 : mah-jong - buffer overflows, denial of service

Nicolas Boullis discovered two vulnerabilities in mah-jong, a network-enabled game. - CAN-2003-0705 buffer overflow This vulnerability could be exploited by a remote attacker to execute arbitrary code with the privileges of the user running the mah-jong server. - CAN-2003-0706 denial of service...

Debian DSA-409-1 : bind - denial of service

A vulnerability was discovered in BIND, a domain name server, whereby a malicious name server could return authoritative negative responses with a large TTL time-to-live value, thereby rendering a domain name unreachable. A successful attack would require that a vulnerable BIND instance submit a...

Debian DSA-382-3 : ssh - possible remote vulnerability

A bug has been found in OpenSSH's buffer handling where a buffer could be marked as grown when the actual reallocation failed. DSA-382-2: This advisory is an addition to the earlier DSA-382-1 advisory: two more buffer handling problems have been found in addition to the one described in DSA-382-1...

Debian DSA-411-1 : mpg321 - format string vulnerability

A vulnerability was discovered in mpg321, a command-line mp3 player, whereby user-supplied strings were passed to printf3 unsafely. This vulnerability could be exploited by a remote attacker to overwrite memory, and possibly execute arbitrary code. In order for this vulnerability to be exploited,...

Debian DSA-393-1 : openssl - denial of service

Dr. Stephen Henson , using a test suite provided by NISCC , discovered a number of errors in the OpenSSL ASN1 code. Combined with an error that causes the OpenSSL code to parse client certificates even when it should not, these errors can cause a denial of service DoS condition on a system using...

Debian DSA-027-1 : OpenSSH - remote exploit

Versions of OpenSSH prior to 2.3.0 are vulnerable to a remote arbitrary memory overwrite attack which may lead to a root exploit. - CORE-SDI has described a problem with regards to RSA key exchange and a Bleichenbacher attack to gather the session key from an ssh session. Both of these issues...

Debian DSA-122-1 : zlib - malloc error (double free)

The compression library zlib has a flaw in which it attempts to free memory more than once under certain conditions. This can possibly be exploited to run arbitrary code in a program that includes zlib. If a network application running as root is linked to zlib, this could potentially lead to a...
