Background ========== Mozilla Firefox is a popular open-source web browser from the Mozilla Project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/mozilla-firefox < 2.0.0.2 *>= 1.5.0.10 >= 2.0.0.2 2 www-client/mozilla-firefox-bin < 2.0.0.2 *>= 1.5.0.10 >= 2.0.0.2 ------------------------------------------------------------------- 2 affected packages on all of their 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" References ========== [ 1 ] CVE-2006-6077 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6077 [ 2 ] CVE-2007-0775 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0775 [ 3 ] CVE-2007-0776 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0776 [ 4 ] CVE-2007-0777 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0777 [ 5 ] CVE-2007-0778 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0778 [ 6 ] CVE-2007-0779 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0779 [ 7 ] CVE-2007-0780 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0780 [ 8 ] CVE-2007-0800 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0800 [ 9 ] CVE-2007-0801 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0801 [ 10 ] CVE-2007-0981 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0981 [ 11 ] CVE-2007-0995 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0995 [ 12 ] Mozilla password loss bug https://bugzilla.mozilla.org/show_bug.cgi?id=360493#c366 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200703-04.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
