Fixed in Apache Tomcat Native Connector 1.2.17

Moderate: Mishandled OCSP invalid response CVE-2018-8019

When using an OCSP responder Tomcat Native 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.

This was fixed in revision 1832832.

Affects: 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34

Important: Mishandled OCSP responses can allow clients to authenticate with revoked certificates CVE-2018-8020

Apache Tomcat Native 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 certicates to connections that require mutual TLS.

This was fixed in revision 1832863.

Affects: 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34
