[GLSA-200805-18] Mozilla products: Multiple vulnerabilities

Background

Mozilla Firefox is an open-source web browser and Mozilla Thunderbird
an open-source email client, both from the Mozilla Project. The
SeaMonkey project is a community effort to deliver production-quality
releases of code derived from the application formerly known as the
'Mozilla Application Suite'. XULRunner is a Mozilla runtime package
that can be used to bootstrap XUL+XPCOM applications like Firefox and
Thunderbird.

Description

The following vulnerabilities were reported in all mentioned Mozilla
products:

• Jesse Ruderman, Kai Engert, Martijn Wargers, Mats Palmgren, and Paul
  Nickerson reported browser crashes related to JavaScript methods,
  possibly triggering memory corruption (CVE-2008-0412).

• Carsten Book, Wesley Garland, Igor Bukanov, moz_bug_r_a4, shutdown,
  Philip Taylor, and tgirmann reported crashes in the JavaScript engine,
  possibly triggering memory corruption (CVE-2008-0413).

• David Bloom discovered a vulnerability in the way images are treated by
  the browser when a user leaves a page, possibly triggering memory
  corruption (CVE-2008-0419).

• moz_bug_r_a4, Boris Zbarsky, and Johnny Stenback reported a series of
  privilege escalation vulnerabilities related to JavaScript
  (CVE-2008-1233, CVE-2008-1234, CVE-2008-1235).

• Mozilla developers identified browser crashes caused by the layout and
  JavaScript engines, possibly triggering memory corruption
  (CVE-2008-1236, CVE-2008-1237).

• moz_bug_r_a4 and Boris Zbarsky discovered that pages could escape from
  its sandboxed context and run with chrome privileges, and inject script
  content into another site, violating the browser's same origin policy
  (CVE-2008-0415).

• Gerry Eisenhaur discovered a directory traversal vulnerability when
  using "flat" addons (CVE-2008-0418).

• Alexey Proskuryakov, Yosuke Hasegawa and Simon Montagu reported
  multiple character handling flaws related to the backspace character,
  the "0x80" character, involving zero-length non-ASCII sequences in
  multiple character sets, that could facilitate Cross-Site Scripting
  attacks (CVE-2008-0416).

The following vulnerability was reported in Thunderbird and SeaMonkey:

• regenrecht (via iDefense) reported a heap-based buffer overflow when rendering an email message with an external MIME body (CVE-2008-0304).

The following vulnerabilities were reported in Firefox, SeaMonkey and
XULRunner:

• The fix for CVE-2008-1237 in Firefox 2.0.0.13 and SeaMonkey 1.1.9 introduced a new crash vulnerability (CVE-2008-1380).

• hong and Gregory Fleischer each reported a
  variant on earlier reported bugs regarding focus shifting in file input
  controls (CVE-2008-0414).

• Gynvael Coldwind (Vexillium) discovered that BMP images could be used
  to reveal uninitialized memory, and that this data could be extracted
  using a "canvas" feature (CVE-2008-0420).

• Chris Thomas reported that background tabs could create a borderless
  XUL pop-up in front of pages in other tabs (CVE-2008-1241).

• oo.rio.oo discovered that a plain text file with a
  "Content-Disposition: attachment" prevents Firefox from rendering
  future plain text files within the browser (CVE-2008-0592).

• Martin Straka reported that the ".href" property of stylesheet DOM
  nodes is modified to the final URI of a 302 redirect, bypassing the
  same origin policy (CVE-2008-0593).

• Gregory Fleischer discovered that under certain circumstances, leading
  characters from the hostname part of the "Referer:" HTTP header are
  removed (CVE-2008-1238).

• Peter Brodersen and Alexander Klink reported that the browser
  automatically selected and sent a client certificate when SSL Client
  Authentication is requested by a server (CVE-2007-4879).

• Gregory Fleischer reported that web content fetched via the "jar:"
  protocol was not subject to network access restrictions
  (CVE-2008-1240).

The following vulnerabilities were reported in Firefox:

• Justin Dolske discovered a CRLF injection vulnerability when storing
  passwords (CVE-2008-0417).

• Michal Zalewski discovered that Firefox does not properly manage a
  delay timer used in confirmation dialogs (CVE-2008-0591).

• Emil Ljungdahl and Lars-Olof Moilanen discovered that a web forgery
  warning dialog is not displayed if the entire contents of a web page
  are in a DIV tag that uses absolute positioning (CVE-2008-0594).

Impact

A remote attacker could entice a user to view a specially crafted web
page or email that will trigger one of the vulnerabilities, possibly
leading to the execution of arbitrary code or a Denial of Service. It
is also possible for an attacker to trick a user to upload arbitrary
files when submitting a form, to corrupt saved passwords for other
sites, to steal login credentials, or to conduct Cross-Site Scripting
and Cross-Site Request Forgery attacks.

Workaround

There is no known workaround at this time.

Resolution

All Mozilla Firefox users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-2.0.0.14"

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

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-2.0.0.14"

All Mozilla Thunderbird users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-2.0.0.14"

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

# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-2.0.0.14"

All SeaMonkey users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/seamonkey-1.1.9-r1"

All SeaMonkey binary users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/seamonkey-bin-1.1.9"

All XULRunner users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/xulrunner-1.8.1.14"

NOTE: The crash vulnerability (CVE-2008-1380) is currently unfixed in
the SeaMonkey binary ebuild, as no precompiled packages have been
released. Until an update is available, we recommend all SeaMonkey
users to disable JavaScript, use Firefox for JavaScript-enabled
browsing, or switch to the SeaMonkey source ebuild.
