Mozilla community member Geoff reported a vulnerability in the way Mozilla opens URL files sent directly to the browser. He demonstrated that such files were opened with local file privileges, giving the remote content access to read from the local filesystem. If a user opened a bookmark to a malicious page in this manner, the page could potentially read from other local files on the user's computer.
