Resolver caches and authoritative zone databases that hold significant
numbers of RRs for the same hostname (of any RTYPE) can suffer from
degraded performance as content is being added or updated, and also when
handling client queries for this name.
This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through
9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.4-S1 through
9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through
9.18.27-S1.

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 |
