Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/ansible-automation-platform-24/eda-controller-rhel8, Red Hat/ansible-automation-platform-25/eda-controller-rhel8, Red Hat/ansible-automation-platform-26/eda-controller-rhel9.
  2. 2Review the reported fix. Source-reported workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Upstream source description

A flaw was found in the containers/storage library. A crafted tar archive containing a malicious whiteout header (e.g. victim/.wh.) can cause the extraction destination directory to be replaced with an arbitrary file when processed by storage/pkg/archive.UnpackLayer, ApplyLayer, or ApplyUncompressedLayer.
