Summary

The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-06:15.ypserv.asc

Insight

Insight

The ypserv(8) utility is a server which distributes NIS databases to client systems within an NIS domain. There are two documented methods of restricting access to NIS maps through ypserv(8): through the use of the /var/yp/securenets file, and through the /etc/hosts.allow file. While both mechanisms are implemented in the server, a change in the build process caused the securenets access restrictions to be inadvertently disabled.

Solution

Solution

Upgrade your system to the appropriate stable release or security branch dated after the correction date https://secure1.securityspace.com/smysecure/catid.html?in=FreeBSD-SA-06:15.ypserv.asc
