Debian DSA-248-1 : hypermail - buffer overflows

Ulf Harnhammar discovered two problems in hypermail, a program to create HTML archives of mailing lists. An attacker could craft a long filename for an attachment that would overflow two buffers when a certain option for interactive use was given, opening the possibility to inject arbitrary code...

Debian DSA-506-1 : neon - buffer overflow

Stefan Esser discovered a problem in neon, an HTTP and WebDAV client library. User input is copied into variables not large enough for all cases. This can lead to an overflow of a static heap variable. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in...

Debian DSA-149-1 : glibc - integer overflow

An integer overflow bug has been discovered in the RPC library used by GNU libc, which is derived from the SunRPC library. This bug could be exploited to gain unauthorized root access to software linking to this code. The packages below also fix integer overflows in the malloc code. They also...

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-298-1 : epic4 - buffer overflows

Timo Sirainen discovered several problems in EPIC4, a popular client for Internet Relay Chat IRC. A malicious server could craft special reply strings, triggering the client to write beyond buffer boundaries. This could lead to a denial of service if the client only crashes, but may also lead to...

Debian DSA-206-1 : tcpdump - denial of service

The BGP decoding routines for tcpdump used incorrect bounds checking when copying data. This could be abused by introducing malicious traffic on a sniffed network for a denial of service attack against tcpdump, or possibly even remote code execution. %NASLMINLEVEL 70300 C Tenable Network Security...

Debian DSA-338-1 : proftpd - SQL injection

runlevel [email protected] reported that ProFTPD's PostgreSQL authentication module is vulnerable to a SQL injection attack. This vulnerability could be exploited by a remote, unauthenticated attacker to execute arbitrary SQL statements, potentially exposing the passwords of other users, or t...

Debian DSA-061-1 : gnupg - printf format attack

The version of GnuPG GNU Privacy Guard, an OpenPGP implementation as distributed in Debian GNU/Linux 2.2 suffers from two problems : - fish stiqz reported on bugtraq that there was a printf format problem in the doget function: it printed a prompt which included the filename that was being...

Debian DSA-326-1 : orville-write - buffer overflows

Orville Write, a replacement for the standard write1 command, contains a number of buffer overflows. These could be exploited to gain either gid tty or root privileges, depending on the configuration selected when the package is installed. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The...

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...

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-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-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-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-422-1 : cvs - remote vulnerability

The account management of the CVS pserver which is used to give remote access to CVS repositories uses a CVSROOT/passwd file in each repository which contains the accounts and their authentication information as well as the name of the local unix account to use when a pserver account is used. Sin...

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-322-1 : typespeed - buffer overflow

typespeed is a game which challenges the player to type words correctly and quickly. It contains a network play mode which allows players on different systems to play competitively. The network code contains a buffer overflow which could allow a remote attacker to execute arbitrary code under the...

Debian DSA-015-1 : sash - broken maintainer script

Versions of the sash package prior to 3.4-4 did not clone /etc/shadow properly, causing it to be made world-readable. This package only exists in stable, so if you are running unstable you won't see a bugfix unless you use the resources from the bottom of this message to the proper configuration...

Debian DSA-059-1 : man-db - symlink attack

Luki R. reported a bug in man-db: it did not handle nested calls ofdropeffectiveprivs and regaineffectiveprivs correctly which would cause it to regain privileges too early. This could be abused to make man create files as user man. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The...

Debian DSA-427-1 : linux-kernel-2.4.17-mips+mipsel - missing boundary check

Paul Starzetz discovered a flaw in bounds checking in mremap in the Linux kernel present in version 2.4.x and 2.6.x which may allow a local attacker to gain root privileges. Version 2.2 is not affected by this bug. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and...
