Synopsis
========

The Mozilla Suite is vulnerable to multiple issues ranging from the
remote execution of arbitrary code to various issues allowing to trick
the user into trusting fake web sites or interacting with privileged
content.

Background
==========

The Mozilla Suite is a popular all-in-one web browser that includes a
mail and news reader.

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

    -------------------------------------------------------------------
     Package                 /  Vulnerable  /               Unaffected
    -------------------------------------------------------------------
  1  www-client/mozilla           < 1.7.6                     >= 1.7.6
  2  www-client/mozilla-bin       < 1.7.6                     >= 1.7.6
    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

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

The following vulnerabilities were found and fixed in the Mozilla
Suite:

* Mark Dowd from ISS X-Force reported an exploitable heap overrun in
  the GIF processing of obsolete Netscape extension 2 (CAN-2005-0399)

* Michael Krax reported that plugins can be used to load privileged
  content and trick the user to interact with it (CAN-2005-0232,
  CAN-2005-0527)

* Michael Krax also reported potential spoofing or
  cross-site-scripting issues through overlapping windows, image or
  scrollbar drag-and-drop, and by dropping javascript: links on tabs
  (CAN-2005-0230, CAN-2005-0231, CAN-2005-0401, CAN-2005-0591)

* Daniel de Wildt and Gael Delalleau discovered a memory overwrite in
  a string library (CAN-2005-0255)

* Wind Li discovered a possible heap overflow in UTF8 to Unicode
  conversion (CAN-2005-0592)

* Eric Johanson reported that Internationalized Domain Name (IDN)
  features allow homograph attacks (CAN-2005-0233)

* Mook, Doug Turner, Kohei Yoshino and M. Deaudelin reported various
  ways of spoofing the SSL "secure site" indicator (CAN-2005-0593)

* Georgi Guninski discovered that XSLT can include stylesheets from
  arbitrary hosts (CAN-2005-0588)

* Secunia discovered a way of injecting content into a popup opened
  by another website (CAN-2004-1156)

* Phil Ringnalda reported a possible way to spoof Install source with
  user:pass@host (CAN-2005-0590)

* Jakob Balle from Secunia discovered a possible way of spoofing the
  Download dialog source (CAN-2005-0585)

* Christian Schmidt reported a potential spoofing issue in HTTP auth
  prompt tab (CAN-2005-0584)

* Finally, Tavis Ormandy of the Gentoo Linux Security Audit Team
  discovered that Mozilla insecurely creates temporary filenames in
  /tmp/plugtmp (CAN-2005-0578)

Impact
======

* The GIF heap overflow could be triggered by a malicious GIF image
  that would end up executing arbitrary code with the rights of the
  user running Mozilla. The other overflow issues, while not thought to
  be exploitable, would have the same impact

* By setting up malicious websites and convincing users to follow
  untrusted links or obey very specific drag-and-drop or download
  instructions, attackers may leverage the various spoofing issues to
  fake other websites to get access to confidential information, push
  users to download malicious files or make them interact with their
  browser preferences

* The temporary directory issue allows local attackers to overwrite
  arbitrary files with the rights of another local user

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Mozilla Suite users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-1.7.6"

All Mozilla Suite binary users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-bin-1.7.6"
