This update fixes bugs and the following security issues:
A specially crafted GSS-TSIG query could cause a buffer overflow in the
ISC implementation of SPNEGO.
named crashed when a DNAME record placed in the ANSWER section during DNAME
chasing turned out to be the final answer to a client query.
Insufficient IXFR checks could result in named serving a zone without an SOA
record at the apex, leading to a RUNTIME_CHECK assertion failure when the
zone was subsequently refreshed. This has been fixed by adding an owner name
check for all SOA records which are included in a zone transfer.
