Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Linux/Linux.
  2. 2Review the reported fix. Update Linux/Linux to d4e0172a1b614373385e9b7111b580f8d2e0b98f; Linux/Linux to 8350819f3e09d494c8178faabe1fc2b18e095a27 if you use the affected versions. Test the change in a non-production environment first.
