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 291c9e137b7c74e8a512cded4845352da4c4adda; Linux/Linux to 884cbf15ccd3980bcc9583073045f91798a86d4e; Linux/Linux to 490c72868443ff90f47f4ccbaaff1eaf8fed46ab; Linux/Linux to 2365b25b4add42bb5f652920b45bc9ad0e35cbc7 if you use the affected versions. Test the change in a non-production environment first.
