Synopsis
========

Mozilla Firefox is vulnerable to a local file deletion issue and to
various issues allowing to trick the user into trusting fake web sites
or interacting with privileged content.

Background
==========

Mozilla Firefox is the popular next-generation browser from the Mozilla
project.

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

    -------------------------------------------------------------------
     Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
  1 net-www/mozilla-firefox < 1.0.1 >= 1.0.1
  2 net-www/mozilla-firefox-bin < 1.0.1 >= 1.0.1
    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

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

The following vulnerabilities were found and fixed in Mozilla Firefox:

* 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
  drag-and-drop, and by dropping javascript: links on tabs
  (CAN-2005-0230, CAN-2005-0231, 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)

* Matt Brubeck reported a possible Autocomplete data leak
(CAN-2005-0589)

* 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)

* Andreas Sanblad from Secunia discovered a possible way of spoofing
the Download dialog using the Content-Disposition header
(CAN-2005-0586)

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

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.

* The overflow issues, while not thought to be exploitable, may allow
a malicious downloaded page to execute arbitrary code with the rights
of the user viewing the page.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Firefox users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-www/mozilla-firefox-1.0.1"

All Firefox binary users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-www/mozilla-firefox-bin-1.0.1"
