Hello Josh, Steve, David, vendors,

   this is due the following vino deficiency:
   [1] https://bugzilla.redhat.com/show_bug.cgi?id=553477#c0
   [2] https://bugzilla.redhat.com/show_bug.cgi?id=678846

As noted in [1] Vino may incorrectly report, that relevant user desktop
is reachable only over local network, when in fact it's reachable from everywhere.

As this is issue slightly on the border, not sure it should receive a CVE identifier,
so Cc-ed David Woodhouse to elaborate more on issue impact if necessary.

Under my opinion, the trust boundary is crossed (it is wrongly reported to the the user, they
have a secure setup, when they do not have it and otherwise would perform steps to correct the
settings). But left the final decision for further discussion.

What are the thoughts of the others? Should this one get a CVE identifier or not?

Claiming that the system is only reachable via local network while
it's not doesn't sound correct to me either. However, how would a
fix look like? A program basically can't know nor reliably determine
whether it's reachable from outside. Private IP addresses are no
indication either. So the only sane thing seems to be to not make
any claims about local networks and just list the IP addresses/host
names of the system.
