Description
In the BIND package, Zone and View names are not validated and thus allow invalid values to be set. For example, a zone name such as ../../../../../../../tmp/badzone can potentially write a file outside the named directory. A similarly named view has the same issue.
These values should be limited to "hostname-like" values (hostnames, FQDNs, IP addresses) as that is generally what BIND expects here.
