According to its self-reported version, the instance of ISC BIND 9 running on the remote name server is less than 9.11.5-P4 / 9.11.5-S5 / 9.12.3-P4 / 9.13.7. It is, therefore, affected by an assertion failure vulnerability.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
