Debian DLA-1108-1 : tomcat7 security update

high Nessus Plugin ID 103430

Synopsis

The remote Debian host is missing a security update.

Description

The Tomcat security team discovered that when using a VirtualDirContext it was possible to bypass security constraints and/or view the source code of JSPs for resources served by the VirtualDirContext using a specially crafted request.

For Debian 7 'Wheezy', these problems have been fixed in version 7.0.28-4+deb7u15.

We recommend that you upgrade your tomcat7 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
