+title = "Stack overflow when resolving addional records from MX or SRV null targets"
+description = """
+There's a stack overflow leading to a crash and potential DOS when processing
+additional records for return of MX or SRV record types from the server.
+
+This is only possible when a zone is configured with a null target for MX or SRV records, i.e. '.'.
+
+Example effected zone record:
+```text
+no-service 86400 IN MX 0 .
+```
+
+Prior to 0.16.0 the additional record processing was not supported by trust-dns-server. There
+Are no known issues with upgrading from 0.16 or 0.17 to 0.18.1. The remidy should be to upgrade to
+0.18.1. If unable to do so, MX, SRV or other record types with a target to the null type, should be avoided.
