Score breakdown

It is possible to construct a zone such that some queries to it will generate responses containing numerous records in the Additional section. An attacker sending many such queries can cause either the authoritative server itself or an independent resolver to use disproportionate resources processing the queries. Zones will usually need to have been deliberately crafted to attack this exposure. This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.32-S1.

Notes


alexmurray

As of isc-dhcp-4.4.3-1, isc-dhcp vendors bind9 libs


mdeslaur

in focal and jammy, isc-dhcp uses the bind9-libs package This is unlikely to affect isc-dhcp’s use of bind9-libs and the vendored bind9 libs, marking as negligible
