Synopsis
========

Multiple vulnerabilities have been found in Apache Tomcat, the worst of
which could lead to privilege escalation.

Background
==========

Apache Tomcat is a Servlet-3.0/JSP-2.2 Container.

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

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 www-servers/tomcat < 8.0.36 >= 7.0.70
>= 8.0.36

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

Multiple vulnerabilities have been discovered in Tomcat. Please review
the CVE identifiers referenced below for details.

Impact
======

A remote attacker may be able to cause a Denial of Service condition,
obtain sensitive information, bypass protection mechanisms and
authentication restrictions.

A local attacker, who is a tomcat’s system user or belongs to tomcat’s
group, could potentially escalate privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Apache Tomcat users have to manually check their Tomcat runscripts
to make sure that they don’t use an old, vulnerable runscript. In
addition:

All Apache Tomcat 7 users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=www-servers/tomcat-7.0.70:7”

All Apache Tomcat 8 users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=www-servers/tomcat-8.0.36:8”
