In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 ->
9.11.35-S1 and 9.16.8-S1 -> 9.16.21-S1 of BIND Supported Preview Edition,
as well as release versions 9.17.0 -> 9.17.18 of the BIND 9.17 development
branch, exploitation of broken authoritative servers using a flaw in
response processing can cause degradation in BIND resolver performance. The
way the lame cache is currently designed makes it possible for its internal
data structures to grow almost infinitely, which may cause significant
delays in client query processing.
