I took a look in the oping source. Without another security flaw, this is just
a bug, oping doesn't do anything while still root that could be an issue. I
agree that it should be fixed, it is a serious bug, but an attacker cannot do
anything nefarious with this flaw.

I'm happy to let Steve overrule me if he wishes, but I'm not going to assign
this a CVE id.
