 Several security vulnerabilities have been found in Tomcat 11, a Java web server and servlet engine. This update improves the handling of HTTP/2 connections and corrects various flaws which can lead to uncontrolled resource consumption and a denial of service.

 For the stable distribution (trixie), these problems have been fixed in version 11.0.15-1~deb13u1.

 We recommend that you upgrade your tomcat11 packages.

 For the detailed security status of tomcat11 please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/tomcat11
