Flawed Opera Causes Some Dissonance

Opera 9 has a heap overflow bug that may cause the browser to crash when it tries to handle a very large link. Opera says they have fixed this in Opera 9.02, and that the impact of the bug is a denial of service attack. They also credit iDefense for finding this bug. According to iDefense, the size of the link only has to top 256 characters, and it can be hidden in an iframe. They also say that attackers can use the bug to run their own code on your computer.
