Debian DSA-3739-1 : tomcat8 - security update

critical Nessus Plugin ID 96018
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

Multiple security vulnerabilities were discovered in the Tomcat servlet and JSP engine, as well as in its Debian-specific maintainer scripts. Those flaws allowed for privilege escalation, information disclosure, and remote code execution.

As part of this update, several regressions stemming from incomplete fixes for previous vulnerabilities were also fixed.

Solution

Upgrade the tomcat8 packages.

For the stable distribution (jessie), these problems have been fixed in version 8.0.14-1+deb8u5.
