For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Sanitize and validate untrusted input to reject unexpected Latin-1 character sequences before passing strings to String.arg() formatting functions. Where possible, restrict network access to services exposing vulnerable string formatting routines.
