   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).
