Synopsis ========
Mozilla Firefox 1.0.2 fixes new security vulnerabilities, including the remote execution of arbitrary code through malicious GIF images or sidebars.
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"
