Description Miloslav Trmač 2011-03-24 18:43:32 UTC
/usr/bin/jwhois in current Fedora 15 (+updates-testing) is group-writable.  This is not really a vulnerability, but it might be easier for an attacker to obtain gid=0 than to obtain uid=0 (at the very least, uid=0 trivially implies the ability to get gid=0).

Therefore I think it is a good idea to could change /usr/bin/jwhois to not be writable by group: it would somewhat increase security of the system, for very little effort.
