Debian DSA-3843-1 : tomcat8 - security update

Medium Nessus Plugin ID 99972

Synopsis

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

Description

Two vulnerabilities were discovered in tomcat8, a servlet and JSP engine.

- CVE-2017-5647 Pipelined requests were processed incorrectly, which could result in some responses appearing to be sent for the wrong request.

- CVE-2017-5648 Some application listeners calls were issued against the wrong objects, allowing untrusted applications running under a SecurityManager to bypass that protection mechanism and access or modify information associated with other web applications.

Solution

Upgrade the tomcat8 packages.

For the stable distribution (jessie), these problems have been fixed in version 8.0.14-1+deb8u9.

For the upcoming stable (stretch) and unstable (sid) distributions, these problems have been fixed in version 8.5.11-2.
