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 :
