CVE-2023-46589 Tomcat 9 did not correctly parse HTTP trailer headers. A trailer header that exceeded the header size limit could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. CVE-2024-24549 Denial of Service due to improper input validation vulnerability for HTTP/2. When processing an HTTP/2 request, if the request exceeded any of the configured limits for headers, the associated HTTP/2 stream was not reset until after all of the headers had been processed. CVE-2024-23672 Denial of Service via incomplete cleanup vulnerability. It was possible for WebSocket clients to keep WebSocket connections open leading to increased resource consumption. For the oldstable distribution (bullseye), these problems have been fixed in version 9.0.43-2~deb11u10. We recommend that you upgrade your tomcat9 packages.
