Debian DSA-3738-1 : tomcat7 - security update

High Nessus Plugin ID 96017

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 tomcat7 packages.

For the stable distribution (jessie), these problems have been fixed in version 7.0.56-3+deb8u6.
