CBL Mariner 2.0 Security Update: cloud-init (CVE-2024-6174)

high Nessus Plugin ID 241872

Synopsis

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

Description

The version of cloud-init 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-2024-6174 advisory.

 - When a non-x86 platform is detected, cloud-init grants root access to a hardcoded url with a local IP address. To prevent this, cloud-init default configurations disable platform enumeration. (CVE-2024-6174)

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.
