IcedTea plugin allows applets to call System.exit()
Last modified: 2009-04-23 15:28:15 EDT
An applet can call System.exit(), which in certain cases will cause the JVM to exit. Thus creating a potential DoS attack, as any other running applets will end up shutting down as well.
The fix is in the upstream repository, and need to be brought into Fedora (10 and Rawhide).
Fixed in all currently supported releases.
