CVE-2017-15698: Fixed an improper handling of fields with more than 127
 bytes which could allow invalid client certificates to be accepted
 (bsc#1078679).

CVE-2018-8019: When using an OCSP responder did not correctly handle
 invalid responses. 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
 (bsc#1103348).

CVE-2018-8020: Did not properly check OCSP pre-produced responses.
 Revoked client certificates may have not been properly identified,
 allowing for users to authenticate with revoked certificates to
 connections that require mutual TLS (bsc#1103347).
