CBL Mariner 2.0 Security Update: docker-buildx / moby-buildx (CVE-2025-0495)

medium Nessus Plugin ID 241944

Synopsis

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

Description

The version of docker-buildx / moby-buildx 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-2025-0495 advisory.

 - Buildx is a Docker CLI plugin that extends build capabilities using BuildKit. Cache backends support credentials by setting secrets directly as attribute values in cache-to/cache-from configuration. When supplied as user input, these secure values May be inadvertently captured in OpenTelemetry traces as part of the arguments and flags for the traced CLI command. OpenTelemetry traces are also saved in BuildKit daemon's history records. This vulnerability does not impact secrets passed to the Github cache backend via environment variables or registry authentication. (CVE-2025-0495)

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.
