Red Hat 5.0 users can upgrade if they like, it won't hurt anything. The versions of bootp, metamail, and dhcpcd distributed with Red Hat 4.2, 5.0, and 5.1 all have security problems. Users of any Red Hat distribution should upgrade their versions of these programs immediately. If you are using dhcpcd on your system, you must restart it before the fix will take effect. Again, sorry for the recent delays in getting these problems fixed.
Viewer discretion is advised.
