Synopsis
========
The help viewer of the Horde Framework allows attackers to execute
arbitrary remote code.
Background
==========
The Horde Application Framework is a general-purpose web application
framework written in PHP, providing classes for handling preferences,
compression, browser detection, connection tracking, MIME and more.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/horde < 3.1.1 >= 3.1.1
Description
===========
Jan Schneider of the Horde team discovered a vulnerability in the help
viewer of the Horde Application Framework that could allow remote code
execution (CVE-2006-1491). Paul Craig reported that "services/go.php"
fails to validate the passed URL parameter correctly (CVE-2006-1260).
Impact
======
An attacker could exploit the vulnerability in the help viewer to
execute arbitrary code with the privileges of the web server user. By
embedding a NULL character in the URL parameter, an attacker could
exploit the input validation issue in go.php to read arbitrary files.
Workaround
==========
There are no known workarounds at this time.
Resolution
==========
All Horde Application Framework users should upgrade to the latest
version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/horde-3.1.1"
