high Nessus Plugin ID 165311


The remote name server is affected by a memory exhaustion vulnerability vulnerability.


The version of ISC BIND installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the cve-2022-38178 advisory.

- By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. (CVE-2022-38178)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to ISC BIND version 9.16.33 / 9.16.33-S1 / 9.18.7 / 9.19.5 or later.
