CBL Mariner 2.0 Security Update: cert-manager (CVE-2024-12401)

medium Nessus Plugin ID 214586

Synopsis

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

Description

The version of cert-manager 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-2024-12401 advisory.

 - A flaw was found in the cert-manager package. This flaw allows an attacker who can modify PEM data that the cert-manager reads, for example, in a Secret resource, to use large amounts of CPU in the cert-manager controller pod to effectively create a denial-of-service (DoS) vector for the cert-manager in the cluster.
 (CVE-2024-12401)

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.
