ISC reports:
An error in zone database reference counting can
lead to an assertion failure if a server which is
running an affected version of BIND attempts
several transfers of a slave zone in quick
succession.
A problem with the implementation of the new
serve-stale feature in BIND 9.12 can lead to
an assertion failure in rbtdb.c, even when
stale-answer-enable is off. Additionally,
problematic interaction between the serve-stale
feature and NSEC aggressive negative caching can
in some cases cause undesirable behavior from named,
such as a recursion loop or excessive logging.
