Package        : tomcat9
CVE ID         : CVE-2021-42340

Apache Tomcat, the servlet and JSP engine, did not properly release an HTTP
upgrade connection for WebSocket connections once the WebSocket connection was
closed. This created a memory leak that, over time, could lead to a denial of
service via an OutOfMemoryError.

For the stable distribution (bullseye), this problem has been fixed in
version 9.0.43-2~deb11u3.

We recommend that you upgrade your tomcat9 packages.
