ISC BIND 9.16.12 < 9.16.48 / 9.16.12-S1 < 9.16.48-S1 / 9.18.0 < 9.18.24 / 9.18.11-S1 < 9.18.24-S1 / 9.19.0 < 9.19.21 Assertion Failure (cve-2023-5679)

high Nessus Plugin ID 190448


The remote name server is affected by an assertion failure 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-2023-5679 advisory.

- A bad interaction between DNS64 and serve-stale may cause `named` to crash with an assertion failure during recursive resolution, when both of these features are enabled. This issue affects BIND 9 versions 9.16.12 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.12-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1. (CVE-2023-5679)

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 9.16.48 / 9.16.48-S1 / 9.18.24 / 9.18.24-S1 / 9.19.21 or later.
