Several vulnerabilities were discovered in the Tomcat servlet and JSP engine, which could result in HTTP request smuggling and code execution in the AJP connector (disabled by default in Debian).

For the oldstable distribution (stretch), these problems have been fixed in version 8.5.54-0+deb9u1.

We recommend that you upgrade your tomcat8 packages.
