    Package        : tomcat9
    CVE ID         : CVE-2019-10072 CVE-2019-12418 CVE-2019-17563
                     CVE-2019-17569 CVE-2020-1935 CVE-2020-1938
    
    Several vulnerabilities were discovered in the Tomcat servlet and JSP
    engine, which could result in HTTP request smuggling, code execution
    in the AJP connector (disabled by default in Debian) or a man-in-the-middle
    attack against the JMX interface.
    
    For the stable distribution (buster), these problems have been fixed in
    version 9.0.31-1~deb10u1. The fix for CVE-2020-1938 may require
    configuration changes when Tomcat is used with the AJP connector, e.g.
    in combination with libapache-mod-jk. For instance the attribute
    "secretRequired" is set to true by default now. For affected setups it's
    recommended to review https://tomcat.apache.org/tomcat-9.0-doc/config/ajp.html
    before the deploying the update.
    
    We recommend that you upgrade your tomcat9 packages.
