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"
