Subject: [announce] Horde 3.0.7 (final)
From: Jan Schneider <jan () horde ! org>
Date: 2005-11-22 17:09:39
The Horde Team is pleased to announce the final release of the Horde
Application Framework version 3.0.7.
This is a security release that fixes cross site scripting vulnerabilities in
two of Horde's MIME viewers. These holes could for example be exploited by an
attacker sending specially crafted emails to Horde's webmail client IMP. The
attack could be used to steal users' identity information, taking over users'
sessions, or changing users' settings.
As a hotfix the css and tgz MIME drivers can be disabled by removing their
entries from the $mime_drivers_map['horde']['registered'] list in
horde/config/mime_drivers.php. Alternatively these two patches could be
applied to lib/Horde/MIME/Viewer/tgz.php and lib/Horde/MIME/Viewer/css.php:
Many thanks to Daniel Schreckling who discovered this vulnerability.
The Horde Application Framework is a modular, general-purpose web application
framework written in PHP. It provides an extensive array of classes that are
targeted at the common problems and tasks involved in developing modern web
