      @dinodaizovi @ioerror @geekable Or if you believe this is a realistic attack, tell her to only visit trusted sites until Apple fix fontd?

      @taviso @dinodaizovi @ioerror @geekable because trusted sites are never owned and malware was never distributed from trusted sites.

      @taviso @dinodaizovi @ioerror @geekable at least in this case, a workaround seems to be a bit complex. It only helps to pressure Apple, IMO.

          @taviso @dinodaizovi @ioerror @geekable tell this to Apple, not to me. I don't think a workaround for this bug is trivial.
