Warning found on port general/icmp

The remote host answered to an ICMP_MASKREQ
query and sent us its netmask.

An attacker can use this information to
understand how your network is set up
and how the routing is done. This may
help him to bypass your filters.

Solution : reconfigure the remote host so
that it does not answer to those requests.
Set up filters that deny ICMP packets of
type 17.

Risk factor : Low
CVE : CAN-1999-0524
