Debian DSA-328-1 : webfs - buffer overflow

webfs, a lightweight HTTP server for static content, contains a buffer overflow whereby a long Request-URI in an HTTP request could cause arbitrary code to be executed. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from...

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-420-1 : jitterbug - improperly sanitised input

Steve Kemp discovered a security related problem in jitterbug, a simple CGI based bug tracking and reporting tool. Unfortunately the program executions do not properly sanitize input, which allows an attacker to execute arbitrary commands on the server hosting the bug database. As mitigating...

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-096-2 : mutt - buffer overflow

Joost Pol found a buffer overflow in the address handling code of mutt a popular mail user agent. Even though this is a one byte overflow this is exploitable. This has been fixed upstream in version 1.2.5.1 and 1.3.25. The relevant patch has been added to version 1.2.5-5 of the Debian package...

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-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-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...

Debian DSA-071-1 : fetchmail - memory corruption

Salvatore Sanfilippo found two remotely exploitable problems infetchmail while doing a security audit. In both the IMAP code and the POP3 code, the input isn't verified even though it's used to store a number in an array. Since no bounds checking is done this can be used by an attacker to write...

Debian DSA-172-1 : tkmail - insecure temporary files

It has been discovered that tkmail creates temporary files insecurely. Exploiting this an attacker with local access can easily create and overwrite files as another user. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted fr...

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-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-162-1 : ethereal - buffer overflow

Ethereal developers discovered a buffer overflow in the ISIS protocol dissector. It may be possible to make Ethereal crash or hang by injecting a purposefully malformed packet onto the wire, or by convincing someone to read a malformed packet trace file. It may be possible to make Ethereal run...

Debian DSA-190-1 : wmaker - buffer overflow

Al Viro found a problem in the image handling code use in Window Maker, a popular NEXTSTEP like window manager. When creating an image it would allocate a buffer by multiplying the image width and height, but did not check for an overflow. This makes it possible to overflow the buffer. This could...

Debian DSA-516-1 : postgresql - buffer overflow

A buffer overflow has been discovered in the ODBC driver of PostgreSQL, an object-relational SQL database, descended from POSTGRES. It is possible to exploit this problem and crash the surrounding application. Hence, a PHP script using php4-odbc can be utilised to crash the surrounding Apache...

Debian DSA-493-1 : xchat - buffer overflow

A buffer overflow has been discovered in the Socks-5 proxy code of XChat, an IRC client for X similar to AmIRC. This allows an attacker to execute arbitrary code on the users' machine. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were...

Debian DSA-469-1 : pam-pgsql - missing input sanitising

Primoz Bratanic discovered a bug in libpam-pgsql, a PAM module to authenticate using a PostgreSQL database. The library does not escape all user-supplied data that are sent to the database. An attacker could exploit this bug to insert SQL statements. %NASLMINLEVEL 70300 C Tenable Network Security...

Debian DSA-441-1 : linux-kernel-2.4.17-mips+mipsel - 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...
