    Package        : tomcat9
    Version        : 9.0.31-1~deb10u11
    CVE ID         : CVE-2023-46589
    Debian Bug     : 1057082

    Apache Tomcat 9, a Servlet and JSP engine, was vulnerable.

    An Improper Input Validation vulnerability was present.
    and Tomcat 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.

    For Debian 10 buster, this problem has been fixed in version
    9.0.31-1~deb10u11.

    We recommend that you upgrade your tomcat9 packages.

    For the detailed security status of tomcat9 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/tomcat9
