DEBIAN-CVE-2025-66614

Improper Input Validation vulnerability.  This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14, from 10.1.0-M1 through 10.1.49, from 9.0.0-M1 through 9.0.112.  The following versions were EOL at the time the CVE was created but are  known to be affected: 8.5.0 through 8.5.100. Older EOL versions are not affected. Tomcat did not validate that the host name provided via the SNI  extension was the same as the host name provided in the HTTP host header  field. If Tomcat was configured with more than one virtual host and the  TLS configuration for one of those hosts did not require client  certificate authentication but another one did, it was possible for a  client to bypass the client certificate authentication by sending  different host names in the SNI extension and the HTTP host header field.    The vulnerability only applies if client certificate authentication is  only enforced at the Connector. It does not apply if client certificate  authentication is enforced at the web application.   Users are recommended to upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fix the issue.
