Description

Mozilla contributor David Bloom reported a vulnerability in the way images are treated by the browser when a user leaves a page which utilizes designMode frames. The reported issue can be used to steal a user's navigation history, forward navigation information, and crash the user's browser. The crash showed evidence of memory corruption and might be exploitable to run arbitrary code.
