"The decision came during the same meeting that the board unanimously
decided to add a new statement to Fedora's legal guidelines concerning
the inclusion of hacking tools....Smith said the language is intended
to clarify its stance on a class of software that can be used both to
secure and penetrate protected networks.
“It's very much a gray area, and as a Board we wanted to ensure that
we were careful and deliberate about the kinds of tools we choose to
put in Fedora,” he explained.
For the record, Fedora already includes a host of other hacking tools,
including Jack John the Ripper, Ettercap, Dsniff, Yersinia, Nessus and
Nikto, to name a small few."
