Debian Security Advisory DSA-4680-1 [email protected]

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.

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