CBL Mariner 2.0 Security Update: unbound (CVE-2024-33655)

high Nessus Plugin ID 208760

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of unbound installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-33655 advisory.

 - The DNS protocol in RFC 1035 and updates allows remote attackers to cause a denial of service (resource consumption) by arranging for DNS queries to be accumulated for seconds, such that responses are later sent in a pulsing burst (which can be considered traffic amplification in some cases), aka the DNSBomb issue. (CVE-2024-33655)

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.
