       An update that fixes three vulnerabilities is now available.
    
    Description:
    
       This update for libtcnative-1-0 to version 1.1.34 fixes the following
       issues:
    
       - 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).
