[SECURITY] CVE-2018-8020 Apache Tomcat Native Connector - Mishandled OCSP responses can allow clients to authenticate with revoked certificates
CVE-2018-8020 Apache Tomcat Native Connector - Mishandled OCSP responses can allow clients to authenticate with revoked certificates Severity: Important Vendor: The Apache Software Foundation Versions Affected: Apache Tomcat Native 1.2.0 to 1.2.16 Apache Tomcat Native 1.1.23 to 1.1.34 Description: 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. Users not using OCSP checks are not affected by this vulnerability. Mitigation: Users of the affected versions should apply one of the following mitigations: - Upgrade to Apache Tomcat 1.2.17 or later Note: This version was included in Apache Tomcat 9.0.10 onwards, 8.5.32 onwards, 8.0.53 onwards and 7.0.90 onwards.

[SECURITY] CVE-2018-8019 Apache Tomcat Native Connector - Mishandled OCSP invalid response
CVE-2018-8019 Apache Tomcat Native Connector - Mishandled OCSP invalid response Severity: Moderate Vendor: The Apache Software Foundation Versions Affected: Apache Tomcat Native 1.2.0 to 1.2.16 Apache Tomcat Native 1.1.23 to 1.1.34 Description: 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. Users not using OCSP checks are not affected by this vulnerability. Mitigation: Users of the affected versions should apply one of the following mitigations: - Upgrade to Apache Tomcat 1.2.17 or later Note: This version was included in Apache Tomcat 9.0.10 onwards, 8.5.32 onwards, 8.0.53 onwards and 7.0.90 onwards.
