This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 throug | |

This causes `named` to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cac | |

The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magni | |

This is not handled correctly and may lead to defeating the RPZ rule. It also may lead to an | |

Authoritative-only servers are generally unaffected, although there are circumstances where authoritative servers may make recursive queries (see: | |
