Versions affected: BIND 9.18.0 When a vulnerable version of named receives a series of specific queries, the named process will eventually terminate due to a failed assertion check.
An assertion check flaw was found in BIND, with a refactoration of RFC 8198 Aggressive Use of the DNSSEC-Validated Cache feature (synth-from-dnssec). The repeated patterns of specific queries to servers with this feature enabled could cause an INSIST failure in query.c:query_dname, which results in unexpected termination. This flaw allows a remote attacker to use a series of specific queries to trigger a failed assertion check that causes the named process to terminate, leading to a d
