Description |
FreeBSD contains a flaw that may allow "securenets" access restrictions to be inadvertantly disabled. The issue is triggered when a change in the build process caused ypserv to fail to load or process the networks and hosts specified in the /var/yp/securenets file. It is possible that the flaw may allow access to NIS maps resulting in a loss of integrity. |

Upgrade to version 5-STABLE or 6-STABLE, or to the RELENG_6_1, RELENG_6_0, RELENG_5_5, RELENG_5_4, or RELENG_5_3 security branch dated after the correction date or higher, as it has been reported to fix this vulnerability. In addition, FreeBSD has released a patch for some older versions. It is also possible to correct the flaw by implementing the following workaround: use /etc/hosts.allow for access control or configure a firewall to restrict access. |
