Oracle was contacted on August 1, 2010.My understanding is that Stefano Di Paola of Minded Security reported this back in April; and further, the feature was a part of reasonably well-documented functionality of Java pretty much ever since: http://download.oracle.com/javase/6/docs/api/java/net/URL.html "Two hosts are considered equivalent if both host names can be resolved into the same IP addresses" This was a pretty horrible design, so it's good to see it gone, though.Eh, you can see where it came from though. Design bugs like this are absolutely miserable to fix (see how we'll never get rebinding out of the browser) and letting identical IP's script against eachother lets an awful lot of legitimate traffic through while blocking almost all attacks. I'm not saying it's a preferred design, but let's reserve "horrible" for things that don't have quite the obvious thought process behind them. Is this, in fact, gone now?/mz _______________________________________________ Full-Disclosure - We believe in it.
