Synopsis
========

An input validation vulnerability has been discovered in Horde-IMP.

Background
==========

Horde-IMP is the Internet Messaging Program. It is written in PHP and
provides webmail access to IMAP and POP3 accounts.

Affected packages
=================

    -------------------------------------------------------------------
     Package            /   Vulnerable   /                  Unaffected
    -------------------------------------------------------------------
  1  net-www/horde-imp       <= 3.2.3                         >= 3.2.4

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

Horde-IMP fails to properly sanitize email messages that contain
malicious HTML or script code.

Impact
======

By enticing a user to read a specially crafted e-mail, an attacker can
execute arbitrary scripts running in the context of the victim's
browser. This could lead to a compromise of the user's webmail account,
cookie theft, etc.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Horde-IMP users should upgrade to the latest stable version:

    # emerge sync

    # emerge -pv ">=horde-imp-3.2.4"
    # emerge ">=horde-imp-3.2.4"
