Nessus server package (nessus-core) violates license
Last modified: 2008-03-31 15:17:26 EDT
Description of problem:
The Nessus server is packaged with OpenSSL support for
current and all past Fedora releases. The license of Nessus
does not permit this.
In fact, the openssl exception of some Nessus modules
does not extend to the actual server:
In directory nessus-core/nessus (the client) you will find:
while in nessus-core/nessusd (the server) you will find only:
Naturally, it does not make much sense to configure package
without SSL support to eliminate the license problem as sensitive
information will get transferred in clear text.
BTW: this mistake was done by virtually any GNU/Linux distribution.
PS: The Nessus-fork OpenVAS (www.openvas.org) has replaced OpenSSL by
GNU/TLS and thus resolves the packaging/distribution problem.
Contacted upstream to see if they can resolve the license incompatibility.
I spoke to upstream, and they don't consider this a problem, because OpenSSL is
widely considered a "system library", thus, it falls under this clause in GPLv2
(there is a similar clause in GPLv3):
However, as a special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary form) with the
major components (compiler, kernel, and so on) of the operating system on which
the executable runs, unless that component itself accompanies the executable.
Admittedly, the fact that they use the exception clause for half of their code,
but not the other half is confusing, but this is acceptable for Fedora.
