Debian DSA-3721-1 : tomcat7 - security update

high Nessus Plugin ID 95034
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 have been discovered in the Tomcat servlet and JSP engine, which may result in possible timing attacks to determine valid user names, bypass of the SecurityManager, disclosure of system properties, unrestricted access to global resources, arbitrary file overwrites, and potentially escalation of privileges.

Solution

Upgrade the tomcat7 packages.

For the stable distribution (jessie), these problems have been fixed in version 7.0.56-3+deb8u5.
