A malicious client can send many DNS messages over TCP, potentially causing
the server to become unstable while the attack is in progress. The server
may recover after the attack ceases. Use of ACLs will not mitigate the
attack.
This issue affects BIND 9 versions 9.18.1 through 9.18.27, 9.19.0 through
9.19.24, and 9.18.11-S1 through 9.18.27-S1.
Notes
| Author | Note |
|---|---|
| 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 This issue doesn’t appear to affect version older than 9.18 |
