| Name | CVE-2017-3138 |
| Description | named contains a feature which allows operators to issue commands to a running server by communicating with the server process over a control channel, using a utility program such as rndc. A regression introduced in a recent feature change has created a situation under which some versions of named can be caused to exit with a REQUIRE assertion failure if they are sent a null command string. Affects BIND 9.9.9->9.9.9-P7, 9.9.10b1->9.9.10rc2, 9.10.4->9.10.4-P7, 9.10.5b1->9.10.5rc2, 9.11.0->9.11.0-P4, 9.11.1b1->9.11.1rc2, 9.9.9-S1->9.9.9-S9. |

Fixed by (9.10.x): https://source.isc.org/cgi-bin/gitweb.cgi?p=bind9.git;a=commitdiff;h=a636604b20cc0aaabc8edbb7595f7c1c820b7610
In practice for any Debian version applying this commit is merely
hardening, since the feature to allow only a subset of "read only"
commands was added only in 9.11.0 and before existing commands permitted
over the control channel were already be given to cause the server to stop.
The CVE-2017-3138 is barely an issue in practice anyway.
