ISC BIND 9.9.3-S1 < 9.16.33-S1 / 9.0.0 < 9.16.33 / 9.16.8-S1 < 9.16.33-S1 / 9.18.0 < 9.18.7 / 9.19.0 < 9.19.5 Vulnerability (cve-2022-2795)

medium Nessus Plugin ID 165312


The remote name server is affected by a 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-2022-2795 advisory.

- By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.

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.
