The security issue is caused due to an error within the handling of "chrome:" URIs. This can be exploited to include arbitrary scripts from local resources via directory traversal attacks. Successful exploitation requires that an extension which doesn't store it's contents inside a .jar file is installed. The security issue is confirmed in version 2.0.0.11 for Windows. Other versions may also be affected. SOLUTION: Do not open untrusted web pages.
