Background ========== Mozilla Firefox is the popular next-generation browser from the Mozilla project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/mozilla-firefox < 1.0.2 >= 1.0.2 2 www-client/mozilla-firefox-bin < 1.0.2 >= 1.0.2 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== The following vulnerabilities were found and fixed in Mozilla Firefox: * Mark Dowd from ISS X-Force reported an exploitable heap overrun in the GIF processing of obsolete Netscape extension 2 (CAN-2005-0399) * Kohei Yoshino discovered that a page bookmarked as a sidebar could bypass privileges control (CAN-2005-0402) * Michael Krax reported a new way to bypass XUL security restrictions through drag-and-drop of items like scrollbars (CAN-2005-0401) Impact ====== * The GIF heap overflow could be triggered by a malicious GIF image that would end up executing arbitrary code with the rights of the user running Firefox * By tricking the user into bookmarking a malicious page as a Sidebar, a remote attacker could potentially execute arbitrary code with the rights of the user running the browser * By setting up a malicious website and convincing users to obey very specific drag-and-drop instructions, attackers may leverage drag-and-drop features to bypass XUL security restrictions, which could be used as a stepping stone to exploit other vulnerabilities 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-1.0.2" All Mozilla Firefox binary users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.0.2" References ========== [ 1 ] CAN-2005-0399 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0399 [ 2 ] CAN-2005-0401 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0401 [ 3 ] CAN-2005-0402 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0402 [ 4 ] Mozilla Security Advisories http://www.mozilla.org/projects/security/known-vulnerabilities.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200503-31.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.
