Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
The Mozilla Foundation has reported numerous security vulnerabilities
related to Mozilla Firefox.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Mozilla Firefox is a redesign of the Mozilla Navigator component. The
goal is to produce a cross-platform stand-alone browser application.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/mozilla-firefox < 1.5.0.5 >=3D 1.5.0.5
2 www-client/mozilla-firefox-bin < 1.5.0.5 >=3D 1.5.0.5
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The following vulnerabilities have been reported:
* Benjamin Smedberg discovered that chrome URL's could be made to
reference remote files.
* Developers in the Mozilla community looked for and fixed several
crash bugs to improve the stability of Mozilla clients.
* "shutdown" reports that cross-site scripting (XSS) attacks could be
performed using the construct XPCNativeWrapper(window).Function(...),
which created a function that appeared to belong to the window in
question even after it had been navigated to the target site.
* "shutdown" reports that scripts granting the UniversalBrowserRead
privilege can leverage that into the equivalent of the far more
powerful UniversalXPConnect since they are allowed to "read" into a
privileged context.
* "moz_bug_r_a4" reports that A malicious Proxy AutoConfig (PAC)
server could serve a PAC script that can execute code with elevated
privileges by setting the required FindProxyForURL function to the
eval method on a privileged object that leaked into the PAC sandbox.
* "moz_bug_r_a4" discovered that Named JavaScript functions have a
parent object created using the standard Object() constructor
(ECMA-specified behavior) and that this constructor can be redefined
by script (also ECMA-specified behavior).
* Igor Bukanov and shutdown found additional places where an untimely
garbage collection could delete a temporary object that was in active
use.
* Georgi Guninski found potential integer overflow issues with long
strings in the toSource() methods of the Object, Array and String
objects as well as string function arguments.
* H. D. Moore reported a testcase that was able to trigger a race
condition where JavaScript garbage collection deleted a temporary
variable still being used in the creation of a new Function object.
* A malicious page can hijack native DOM methods on a document object
in another domain, which will run the attacker's script when called
by the victim page.
* Secunia Research has discovered a vulnerability which is caused due
to an memory corruption error within the handling of simultaneously
happening XPCOM events. This leads to use of a deleted timer object.
* An anonymous researcher for TippingPoint and the Zero Day
Initiative showed that when used in a web page Java would reference
properties of the window.navigator object as it started up.
* Thilo Girmann discovered that in certain circumstances a JavaScript
reference to a frame or window was not properly cleared when the
referenced content went away.
Impact
=3D=3D=3D=3D=3D=3D
A user can be enticed to open specially crafted URLs, visit webpages
containing malicious JavaScript or execute a specially crafted script.
These events could lead to the execution of arbitrary code, or the
installation of malware on the user's computer.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All Mozilla Firefox users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=3Dwww-client/mozilla-firefox-1.5.0.5"
Users of the binary package should upgrade as well:
# emerge --sync
# emerge --ask --oneshot --verbose
">=3Dwww-client/mozilla-firefox-bin-1.5.0.5"
