Synopsis
========

Improper file ownership may allow a member of the tomcat group to
execute scripts as root.

Background
==========

Tomcat is the Apache Jakarta Project's official implementation of Java
Servlets and Java Server Pages.

Affected packages
=================

    -------------------------------------------------------------------
     Package         /   Vulnerable   /                     Unaffected
    -------------------------------------------------------------------
  1  net-www/tomcat      < 5.0.27-r3                      >= 5.0.27-r3
                                                         *>= 4.1.30-r4
                                                          *>= 3.3.2-r2

Description
===========

The Gentoo ebuild for Tomcat sets the ownership of the Tomcat init
scripts as tomcat:tomcat, but those scripts are executed with root
privileges when the system is started. This may allow a member of the
tomcat group to run arbitrary code with root privileges when the Tomcat
init scripts are run.

Impact
======

This could lead to a local privilege escalation or root compromise by
authenticated users.

Workaround
==========

Users may change the ownership of /etc/init.d/tomcat* and
/etc/conf.d/tomcat* to be root:root:

    # chown -R root:root /etc/init.d/tomcat*
    # chown -R root:root /etc/conf.d/tomcat*

Resolution
==========

All Tomcat users can upgrade to the latest stable version, or simply
apply the workaround:

    # emerge sync
    # emerge -pv ">=net-www/tomcat-5.0.27-r3"
    # emerge ">=net-www/tomcat-5.0.27-r3"

============
