Security Fixes 9.8.0-P4 * Using Response Policy Zone (RPZ) with DNAME records and querying the subdomain of that label can cause named to crash. Now logs that DNAME is not supported. [RT #24766] * If named is configured to be both authoritative and resursive and receives a recursive query for a CNAME in a zone that it is authoritative for, if that CNAME also points to a zone the server is authoritative for, the recursive part of name will not follow the CNAME change and the response will not be a complete CNAME chain. [RT #24455] * Using Response Policy Zone (RPZ) to query a wildcard CNAME label with QUERY type SIG/RRSIG, it can cause named to crash. Fix is query type independant. [RT #24715] [CVE-2011-1907] * Change #2912 (see CHANGES) exposed a latent bug in the DNS message processing code that could allow certain UPDATE requests to crash named. This was fixed by disambiguating internal database representation vs DNS wire format data. [RT #24777] [CVE-2011-2464] Thank You Thank you to everyone who assisted us in making this release possible.
