Background ========== Mozilla is a popular web browser that includes a mail and newsreader. Galeon and Epiphany are both web browsers that use gecko, the Mozilla rendering engine. Mozilla Firefox is the next-generation browser from the Mozilla project that incorporates advanced features that are yet to be incorporated into Mozilla. Mozilla Thunderbird is the next-generation mail client from the Mozilla project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mozilla < 1.7.2 >= 1.7.2 2 mozilla-firefox < 0.9.3 >= 0.9.3 3 mozilla-thunderbird < 0.7.3 >= 0.7.3 4 mozilla-bin < 1.7.2 >= 1.7.2 5 mozilla-firefox-bin < 0.9.3 >= 0.9.3 6 mozilla-thunderbird-bin < 0.7.3 >= 0.7.3 7 epiphany < 1.2.7-r1 >= 1.2.7-r1 8 galeon < 1.3.17 >= 1.3.17 ------------------------------------------------------------------- 8 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Mozilla, Galeon, Epiphany, Mozilla Firefox and Mozilla Thunderbird contain the following vulnerabilities: * All Mozilla tools use libpng for graphics. This library contains a buffer overflow which may lead to arbitrary code execution. * If a user imports a forged Certificate Authority (CA) certificate, it may overwrite and corrupt the valid CA already installed on the machine. Mozilla, Mozilla Firefox, and other gecko-based browsers also contain a bug in their caching which may allow the SSL icon to remain visible, even when the site in question is an insecure site. Impact ====== Users of Mozilla, Mozilla Firefox, and other gecko-based browsers are susceptible to SSL certificate spoofing, a Denial of Service against legitimate SSL sites, crashes, and arbitrary code execution. Users of Mozilla Thunderbird are susceptible to crashes and arbitrary code execution via malicious e-mails. Workaround ========== There is no known workaround for most of these vulnerabilities. All users are advised to upgrade to the latest available version. Resolution ========== All users should upgrade to the latest stable version: # emerge sync # emerge -pv your-version # emerge your-version References ========== [ 1 ] CAN-2004-0763 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0763 [ 2 ] CAN-2004-0758 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0758 [ 3 ] CAN-2004-0597 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0597 [ 4 ] CAN-2004-0598 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0598 [ 5 ] CAN-2004-0599 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0599 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200408-22.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.
