FreeBSD : powerdns-recursor -- denial of service (28b69630-9b10-11ed-97a6-6805ca2fa271)

high Nessus Plugin ID 170474

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 28b69630-9b10-11ed-97a6-6805ca2fa271 advisory.

 - A remote attacker might be able to cause infinite recursion in PowerDNS Recursor 4.8.0 via a DNS query that retrieves DS records for a misconfigured domain, because QName minimization is used in QM fallback mode. This is fixed in 4.8.1. (CVE-2023-22617)

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

Solution

Update the affected packages.
