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 | |

Typically these servers will be found in Active Directory integrated DNS deployments | |

An attacker sending many such queries can cause either the authoritative server itself or an independent resolver to use disproportionate | |
