Description
Detection of Error Condition Without Action vulnerability in Apache Tomcat when configuring Certificate Revocation List (CRLs) for a FFM based connector. If an FFM connector was configured with invalid CRLs, the invalid CRLs were ignored meaning invalid certificates could be accepted.

Users are recommended to upgrade to version 11.0.23, 10.1.56 or 9.0.119, which fixes the issue.
