Synopsis
========

Multiple vulnerabilities in the Horde Application Framework may lead to
the execution of arbitrary files, information disclosure, and allow a
remote attacker to bypass security restrictions.

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.

=================

Description
===========

Multiple vulnerabilities have been reported in the Horde Application
Framework:

* David Collins, Patrick Pelanne and the HostGator.com LLC support
  team discovered that the theme preference page does not sanitize POST
  variables for several options, allowing the insertion of NULL bytes
  and ".." sequences (CVE-2008-1284).

* An error exists in the Horde API allowing users to bypass security
  restrictions.

Impact
======

The first vulnerability can be exploited by a remote attacker to read
arbitrary files and by remote authenticated attackers to execute
arbitrary files. The second vulnerability can be exploited by
authenticated remote attackers to perform restricted operations.

Workaround
==========

There is no known workaround at this time.

==========

version:

   # emerge --sync
   # emerge --ask --oneshot --verbose ">=www-apps/horde-3.1.7"
