There appears to be a bit of confusion out there. To be clear: 1. The two bugs that were fixed in OpenSSL 1.1.1k [1] were introduced well after the fork, so LibreSSL is not affected. OpenSSL have kindly given us advance access to their fixes.
2. The bug fixed in LibreSSL 3.2.5 [2] is our own and entirely unrelated. [1]: https://marc.info/?l=openssl-announce&m=161668124700970&w=2 [2]: https://marc.info/?l=openbsd-announce&m=161582456312832&w=2
