Mozilla Firefox 1.07
Mozilla.org has released to IDG News Service: "Links pointing to a host with a long name composed entirely of dashes can be crafted so that earlier versions of Firefox will execute arbitrary code of an attacker's choosing. This means that an attacker theoretically could use the flaw to take control of a user's machine, by launching what is called a buffer overflow attack." Version 1.0.7 also fixes a critical flaw in the way the Mozilla software handles Unix and Linux shell commands that could allow attackers to run unauthorized software on some systems, according to the report.
