Package : tomcat9 Version : 9.0.31-1~deb10u12 CVE ID : CVE-2024-23672 CVE-2024-24549 Debian Bug : 1066877 1066878

Two security vulnerabilities have been discovered in the Tomcat servlet and JSP engine.

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 Debian 10 buster, these problems have been fixed in version 9.0.31-1~deb10u12.

We recommend that you upgrade your tomcat9 packages.
