From tsl@trustix.org Tue Nov 16 19:48:55 2004 From: Trustix Security Advisor To: bugtraq@securityfocus.com Date: Tue, 16 Nov 2004 15:25:56 +0100 Subject: TSLSA-2004-0058 - multi -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Trustix Secure Linux Security Advisory #2004-0058 Package name: gd samba sqlgrey sudo Summary: Various security fixes Date: 2004-11-15 Affected versions: Trustix Secure Linux 1.5 Trustix Secure Linux 2.0 Trustix Secure Linux 2.1 Trustix Secure Linux 2.2 Trustix Operating System - Enterprise Server 2 - -------------------------------------------------------------------------- Package description: gd: gd is a graphics library. It allows your code to quickly draw images complete with lines, arcs, text, multiple colors, cut and paste from other images, and flood fills, and write out the result as a PNG or JPEG file. This is particularly useful in World Wide Web applications, where PNG and JPEG are two of the formats accepted for inline images by most browsers. samba: Samba provides an SMB server which can be used to provide network services to SMB (sometimes called "Lan Manager") clients, including various versions of MS Windows, OS/2, and other Linux machines sqlgrey: SQLgrey is a Postfix grey-listing policy service with auto-white-listing written in Perl with SQL database as storage backend. sudo: Sudo (superuser do) allows a system administrator to give certain users (or groups of users) the ability to run some (or all) commands as root while logging all commands and arguments. Sudo operates on a per-command basis. It is not a replacement for the shell. Features include: the ability to restrict what commands a user may run on a per-host basis, copious logging of each command (providing a clear audit trail of who did what), a configurable timeout of the sudo command, and the ability to use the same configuration file (sudoers) on many different machines. Problem description: gd: There has been found serveral overflows in gd. This can be used to execute arbitary code in programs using the gd library. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0941 and CAN-2004-0990 to these issues. sqlgrey: Matt Linzbach made us aware that the maintainers of SQLgrey have issued a new release that fixes an SQL injection bug. samba: From the Samba advisory: Invalid bounds checking in reply to certain trans2 requests could result in a buffer overrun in smbd. In order to exploit this defect, the attacker must be able to create files with very specific Unicode filenames on the Samba share. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0882 to this issue. From the Samba advisory: A bug in the input validation routines used to match filename strings containing wildcard characters may allow a user to consume more than normal amounts of CPU cycles thus impacting the performance and response of the server. In some circumstances the server can become entirely unresponsive. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0930 to this issue. sudo: Bash exported functions and the CDPATH variable are now stripped from the environment passed to the program to be executed. Action: We recommend that all systems with this package installed be upgraded. Please note that if you do not need the functionality provided by this package, you may want to remove it from your system.
