Detail

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.
