Background ========== Mozilla Firefox is the next-generation web browser from the Mozilla project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/mozilla-firefox < 1.0.5 >= 1.0.5 2 www-client/mozilla-firefox-bin < 1.0.5 >= 1.0.5 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== The following vulnerabilities were found and fixed in Mozilla Firefox: * "moz_bug_r_a4" and "shutdown" discovered that Firefox was improperly cloning base objects (MFSA 2005-56). * Michael Krax reported that Firefox was not correctly handling JavaScript URLs from external applications (MFSA 2005-53), and that the "Set as wallpaper" function in versions 1.0.3 and 1.0.4 could be abused to load JavaScript (MFSA 2005-47). * Several researchers reported ways to trick Firefox into accepting events generated by web content (MFSA 2005-45). * Kohei Yoshino discovered a new way to inject script from the sidebar panel using data: (MFSA 2005-49). * "moz_bug_r_a4" reported that Firefox failed to validate XHTML DOM nodes properly (MFSA 2005-55), and that XBL scripts ran even when Javascript is disabled (MFSA 2005-46). * "shutdown" discovered a possibly exploitable crash in InstallVersion.compareTo (MFSA 2005-50). * Finally, Secunia discovered that a child frame can call top.focus() even if the framing page comes from a different origin and has overridden the focus() routine (MFSA 2005-52), and that the frame injection spoofing bug fixed in 1.0.2 was mistakenly reintroduced in 1.0.3 and 1.0.4 (MFSA 2005-51). Impact ====== A remote attacker could craft malicious web pages that would leverage these issues to inject and execute arbitrary script code with elevated privileges, steal cookies or other information from web pages, or spoof content. Workaround ========== There are no known workarounds for all the issues at this time. Resolution ========== All Mozilla Firefox users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.0.5" All Mozilla Firefox binary users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.0.5" References ========== [ 1 ] Mozilla Foundation Security Advisories http://www.mozilla.org/projects/security/known-vulnerabilities.html#Firefox Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200507-14.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.
