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.
