**Name of the Vulnerable Software and Affected Versions** FreeBSD versions 5.3 through 6.1 **Description** The issue concerns the build process for ypserv, which inadvertently disables access restrictions when utilizing the /var/yp/securenets file. This allows remote attackers to bypass intended access restrictions. **Recommendations** For FreeBSD versions 5.3 through 6.1, consider re-enabling access restrictions by properly configuring the /var/yp/securenets file to minimize the risk of exploitation.
