Second hunk from secrity fix from google.
The hunk is not fully understood but it just makes a check tighter so its
safer for us to apply until it is fully understood.

Might fix issue 2550 (and Chrome issue 68115 and unknown CERT issues).
Our bugtracker issue though should stay open until this has been fully
investiagted
