1581569: CVE-2018-8020 tomcat-native: Mishandled OCSP responses can allow clients to authenticate with revoked certificates
When using pre-produced responses from an OCSP responder, Tomcat Native did not correctly validate the status of certificates. This allowed for revoked client certificates to be incorrectly identified. It was therefore possible for users to authenticate with revoked certificates when using mutual TLS.
