Debian DSA-3843-1 : tomcat8 - security update

critical Nessus Plugin ID 99972
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.

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.
