Background ========== Mozilla Firefox is a redesign of the Mozilla Navigator component. The goal is to produce a cross-platform stand-alone browser application. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/mozilla-firefox < 1.5.0.5 >= 1.5.0.5 2 www-client/mozilla-firefox-bin < 1.5.0.5 >= 1.5.0.5 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== 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 ====== 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 ========== 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-1.5.0.5" Users of the binary package should upgrade as well: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.5.0.5" References ========== [ 1 ] CVE-2006-3113 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3113 [ 2 ] CVE-2006-3677 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3677 [ 3 ] CVE-2006-3801 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3801 [ 4 ] CVE-2006-3802 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3802 [ 5 ] CVE-2006-3803 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3803 [ 6 ] CVE-2006-3805 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3805 [ 7 ] CVE-2006-3806 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3806 [ 8 ] CVE-2006-3807 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3807 [ 9 ] CVE-2006-3808 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3808 [ 10 ] CVE-2006-3809 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3809 [ 11 ] CVE-2006-3810 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3810 [ 12 ] CVE-2006-3811 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3811 [ 13 ] CVE-2006-3812 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3812 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200608-03.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.
