BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported
Preview Editions: 9.11.4-S1 -> 9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions
of BIND 9 earlier than those shown - back to 9.1.0, including Supported
Preview Editions - are also believed to be affected but have not been
tested as they are EOL. The cache could become poisoned with incorrect
records leading to queries being made to the wrong servers, which might
also result in false information being returned to clients.
