Multiple security vulnerabilities have been discovered in Tomcat 9, a Java
based web server, servlet and JSP engine which may result in a denial of
service, authentication bypass or the disclosure of sensitive information.
In order to address certain vulnerabilities and restore the compatibility with
Tomcat 9, an upgrade of the Tomcat native library, libtcnative-1, was required
as well.
Although we are not aware of any problems, new upstream versions may introduce
new options, limits or code changes which may or may not affect your existing
web applications. We recommend to consult the Tomcat 9 documentation for
further information.
For Debian 11 bullseye, these problems have been fixed in version
9.0.118-0+deb11u1.
We recommend that you upgrade your tomcat9 packages.
For the detailed security status of tomcat9 please refer to
its security tracker page at:
