Title:	Mozilla Firefox: Multiple vulnerabilities
Date:	03/02/2007
Bugs:	#165555
ID:	200703-04

Synopsis

Multiple vulnerabilities have been reported in Mozilla Firefox, some of which may allow user-assisted arbitrary remote code execution.

Background

Mozilla Firefox is a popular open-source web browser from the Mozilla Project.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-client/mozilla-firefox	< 2.0.0.2	>= 1.5.0.10	All supported architectures
www-client/mozilla-firefox-bin	< 2.0.0.2	>= 1.5.0.10	All supported architectures

Description

Tom Ferris reported a heap-based buffer overflow involving wide SVG stroke widths that affects Mozilla Firefox 2 only. Various researchers reported some errors in the JavaScript engine potentially leading to memory corruption. Mozilla Firefox also contains minor vulnerabilities involving cache collision and unsafe pop-up restrictions, filtering or CSS rendering under certain conditions.

Impact

An attacker could entice a user to view a specially crafted web page that will trigger one of the vulnerabilities, possibly leading to the execution of arbitrary code. It is also possible for an attacker to spoof the address bar, steal information through cache collision, bypass the local files protection mechanism with pop-ups, or perform cross-site scripting attacks, leading to the exposure of sensitive information, like user credentials.

Workaround

There is no known workaround at this time for all of these issues, but most of them can be avoided by disabling JavaScript.

Resolution

Users upgrading to the following releases of Mozilla Firefox should note that this upgrade has been found to lose the saved passwords file in some cases. The saved passwords are encrypted and stored in the 'signons.txt' file of ~/.mozilla/ and we advise our users to save that file before performing the upgrade.

All Mozilla Firefox 1.5 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.5.0.10"

All Mozilla Firefox 1.5 binary users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.5.0.10"

All Mozilla Firefox 2.0 users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-2.0.0.2"

All Mozilla Firefox 2.0 binary users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-2.0.0.2"
