ICMP echo (ping) is allowed from arbitrary hosts.

Find out more about CVE-1999-0523 from the MITRE CVE dictionary dictionary and NIST NVD.

Statement

Red Hat Enterprise Linux by default does respond to ICMP echo requests, although it's likely that in a production environment those would be filtered by some firewall on entry to your network. However you can happily block ICMP ping responses using iptables if you so wish, but note that there is no known vulnerability in allowing them.
