IRIX rpc.mountd contains a flaw that may allow a denial of service. The issue is triggered when rpc.mountd incorrectly denies access to anonymous clients whose hostname is not listed in DNS, NIS or /etc/hosts. If an attacker were able to manipulate one of these naming services it could result in loss of availability to the service for some users.
