Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 has a flaw that
does not properly check OCSP pre-produced responses, which are lists
(multiple entries) of certificate statuses. Subsequently, revoked client
certificates may not be properly identified, allowing for users to
authenticate with revoked certificates to connections that require mutual
TLS. Users not using OCSP checks are not affected by this vulnerability.
