    Multiple security vulnerabilities have been discovered in Tomcat 10, a Java
    based web server, servlet and JSP engine which may result in a denial of
    service, authentication bypass or the disclosure of sensitive information.

    Although we are not aware of any problems, new upstream versions may introduce
    new options, limits or code changes which may or may not affect your existing
    web applications. We recommend to consult the Tomcat 10 documentation for
    further information.

    For the oldstable distribution (bookworm), these problems have been fixed
    in version 10.1.55-1~deb12u1.

    For the stable distribution (trixie), these problems have been fixed in
    version 10.1.55-1~deb13u1.

    We recommend that you upgrade your tomcat10 packages.

    For the detailed security status of tomcat10 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/tomcat10

    Further information about Debian Security Advisories, how to apply
    these updates to your system and frequently asked questions can be
