Nah, it's doing great. I think you ran into an obscure bug in Ubuntu:
/bin/ping has to be privileged to access the ICMP functions,  and used
to be  SUID root. Now, however, it's using capabilities, which are not
that well displayed (the only indication from 'ls' is red background,
not explained anywhere). You have to know what to look for:

getcap /bin/ping
/bin/ping = cap_net_admin,cap_net_raw+ep

I can't check now but I bet you that on your system it will not have
those capabilities ---  or they will be for some reason ignored by the
kernel.
