No one knows that LibreSSL is affected by CVE-2018-12404, CVE-2018-19608, CVE-2018-16868, CVE-2018-16869, and CVE-2018-16870 or not.

Does anybody has any info about it?

  • $\begingroup$ The authors didn't test it. Actually as pointed out Gilles in the comments of this answer surely the first mitigation should be keeping your system up-to-date? Therefore if you don't support TLS 1.2 you are safe. $\endgroup$

    $\begingroup$ You are referencing various CVE which are not related to a TLS 1.3 downgrade but your title only asks about TLS 1.3 downgrade. Please make clear what you actually want to know. As for what you ask in the title: LibreSSL is not affected by TLS 1.3 downgrade since it does not support TLS 1.3 yet. $\endgroup$ Feb 8 '19 at 12:29

LibreSSL doesn't support TLS 1.3.
