1. Very large RRSIG RRsets included in a negative cache can trigger an assertion failure that will crash named (BIND 9 DNS) due to an off-by-one error in a buffer size check. This bug affects all resolving name servers, whether DNSSEC validation is enabled or not, on all BIND versions prior to today. There is a possibility of malicious exploitation of this bug by remote users. 2. Named could fail to validate zones listed in a DLV that validated insecure without using DLV and had DS records in the parent zone. Add a patch provided by ru@ and confirmed by ISC to fix a crash at shutdown time when a SIG(0) key is being used.
