FreeBSD : powerdns-recursor -- Denial of Service (67793feb-0b5b-11f1-a1c0-0050569f0b83)

high Nessus Plugin ID 299351

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 multiple vulnerabilities as referenced in the 67793feb-0b5b-11f1-a1c0-0050569f0b83 advisory.

PowerDNS Team reports:
2025-07: Internal logic flaw in cache management can lead to a denial of service in Recursor 2025-08: Insufficient validation of incoming notifies over TCP can lead to a denial of service in Recursor 2026-01: Crafted zones can lead to increased resource usage in Recursor 2026-01: This problem can be triggered by publishing and querying a crafted zone that causes large memory usage.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

Solution

Update the affected packages.
