The culprit is more around iputils-ping, since capabilities seem to have been missing for /bin/ping
The correct setting should be :
# getcap /bin/ping
/bin/ping = cap_net_raw+ep
Otherwise, doing this will solve it :
# apt-get install --reinstall iputils-ping
Not sure exactly what led to an upgraded system where that was missing... but maybe the workaround will be useful for some others.
Hope this helps,
