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 a64284b9e1999ad5580debced4bc6d6adb28aad4; Linux/Linux to 15403445b873a4ce45b2d4ecfb5928a025297282; Linux/Linux to 1de84b6d65a7df30b5edc7208f828c4ecc8a7154 if you use the affected versions. Test the change in a non-production environment first.
