Debian DSA-4680-1 : tomcat9 - security update

critical Nessus Plugin ID 136376
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


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.


Upgrade the tomcat9 packages.

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 the deploying the update.
