Package        : tomcat10
CVE ID         : CVE-2023-46589 CVE-2024-23672 CVE-2024-24549
Debian Bug     : 1057082 1066877 1066878

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

CVE-2023-46589

    Tomcat 10 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 stable distribution (bookworm), these problems have been fixed in
version 10.1.6-1+deb12u2.

We recommend that you upgrade your tomcat10 packages.
