OpenBSD 5.9 Errata for OCSP available

This errata fixes several issues in the OCSP code that could result in
the incorrect generation and parsing of OCSP requests. This remediates
a lack of error checking on time parsing in these functions, and
ensures that only
GENERALIZEDTIME formats are accepted for OCSP, as per RFC 6960.

Issues reported, and fixes provided by Kazuki Yamaguchi <>
