Comment 1 Jan Lieskovsky 2008-12-09 09:54:26 UTC
This issue affects the versions of the tor package, as shipped 
with Fedora releases of 8,9 and 10. 

Please upgrade to latest upstream version of apply the above patch.

(In reply to comment #2)
> All current Fedora versions are already updated to upstream version 0.2.0.23:

Bah, 0.2.0.32 that should be, of course...

Comment 4 Enrico Scholz 2008-12-09 13:35:52 UTC
fwiw, this bug never affected any tor version shipped by fedora.
There was always a patch like

http://cvs.fedora.redhat.com/viewvc/rpms/tor/F-7/tor-0.1.1.26-setgroups.patch?revision=1.1&root=extras&view=markup

dropping supplementary groups.
