Amazon Linux 2 : docker, --advisory ALAS2ECS-2025-076 (ALASECS-2025-076)

medium Nessus Plugin ID 271757

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of docker installed on the remote host is prior to 25.0.13-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2025-076 advisory.

Moby is an open source container framework developed by Docker Inc. that is distributed as Docker Engine, Mirantis Container Runtime, and various other downstream projects/products. A firewalld vulnerability affects Moby releases before 28.0.0. When firewalld reloads, Docker fails to re-create iptables rules that isolate bridge networks, allowing any container to access all ports on any other container across different bridge networks on the same host. This breaks network segmentation between containers that should be isolated, creating significant risk in multi-tenant environments. Only containers in --internal networks remain protected.Workarounds include reloading firewalld and either restarting the docker daemon, re-creating bridge networks, or using rootless mode. Maintainers anticipate a fix for this issue in version 25.0.13. (CVE-2025-54410)

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

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

Solution

Run 'yum update docker' or or 'yum update --advisory ALAS2ECS-2025-076' to update your system.
