CVE-2017-3138 Information

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.
