Mozilla Firefox is the popular next-generation browser from the
Mozilla project.
The following vulnerabilities were found and fixed in Mozilla
<li>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)</li>
<li>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)</li>
<li>Daniel de Wildt
and Gael Delalleau discovered a memory overwrite in a string library
<li>Wind Li discovered a possible heap overflow in
UTF8 to Unicode conversion (CAN-2005-0592)</li>
<li>Eric Johanson
reported that Internationalized Domain Name (IDN) features allow
homograph attacks (CAN-2005-0233)</li>
<li>Mook, Doug Turner, Kohei
Yoshino and M. Deaudelin reported various ways of spoofing the SSL
"secure site" indicator (CAN-2005-0593)</li>
<li>Matt Brubeck reported
a possible Autocomplete data leak (CAN-2005-0589)</li>
Guninski discovered that XSLT can include stylesheets from arbitrary
hosts (CAN-2005-0588)</li>
<li>Secunia discovered a way of injecting
content into a popup opened by another website (CAN-2004-1156)</li>
<li>Phil Ringnalda reported a possible way to spoof Install source with
user:pass@host (CAN-2005-0590)</li>
<li>Jakob Balle from Secunia
discovered a possible way of spoofing the Download dialog source
<li>Christian Schmidt reported a potential
spoofing issue in HTTP auth prompt tab (CAN-2005-0584)</li>
Sanblad from Secunia discovered a possible way of spoofing the Download
dialog using the Content-Disposition header (CAN-2005-0586)</li>
<li>Finally, Tavis Ormandy of the Gentoo Linux Security Audit Team
discovered that Firefox insecurely creates temporary filenames in
/tmp/plugtmp (CAN-2005-0578)</li>
<impact type="normal">
<li>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.</li>
<li>The temporary directory issue allows
local attackers to overwrite arbitrary files with the rights of another
local user.</li>
<li>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.</li>
There is no known workaround at this time.
All Firefox users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/mozilla-firefox-1.0.1&quot;</code>
All Firefox binary users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/mozilla-firefox-bin-1.0.1&quot;</code>
