Comment 3 Marc Schoenefeld 2009-08-06 15:01:48 UTC
The WebStart (javaws) that ships with IcedTea in Fedora has a  flaw 
in its security model, which allows it to run unsigned code as signed under 
some cases.

What happens is that the current NetX code assumes that the entire
application is trusted if any of the listed jars are. This means that if
someone puts a signed jar whose cert has already been permanently
accepted, NetX will run the untrusted code as trusted, too.
