Briefly, we prefer confidential issue on gitlab (not github). An issue is much better, because it's easier to get more ISC engineers involved in it, evolve the case as more information is known, update or extra information, etc.

Second best is to send e-mail (possibly encrypted) to [email protected].

ISC treats the security of its software products very seriously. This document discusses the evaluation of a defect severity and the process in detail: https://kb.isc.org/docs/aa-00861
