Test ID:1.3.6.1.4.1.25623.1.0.56851
Category:FreeBSD Local Security Checks
Title:FreeBSD Security Advisory (FreeBSD-SA-06:15.ypserv.asc)
Summary:The remote host is missing an update to the system; as announced in the referenced advisory FreeBSD-SA-06:15.ypserv.asc
Description:Summary:
The remote host is missing an update to the system
as announced in the referenced advisory FreeBSD-SA-06:15.ypserv.asc

Vulnerability 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:
Upgrade your system to the appropriate stable release
or security branch dated after the correction date.

CVSS Score:
6.4
