Mistaken assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records could lead to a situation in which named would exit with an assertion failure when processing a response in which records occurred in an unusual order. Affects BIND 9.9.9-P6, 9.9.10b1->9.9.10rc1, 9.10.4-P6, 9.10.5b1->9.10.5rc1, 9.11.0-P3, 9.11.1b1->9.11.1rc1, and 9.9.9-S8.
CVSS 3 base score: 7.5
in bind9 9.9 and earlier, with the bind9 patch for this issue applied, named will hit another assertion; to fix that requires the lib/dns/named.c change from https://source.isc.org/cgi-bin/gitweb.cgi?p=bind9.git;a=commitdiff;h=dc3912f3caac1104fef441fd18571b7a975708ea
