which allowing to read, modify and overwrite arbitrary files.

Background
==========

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

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  www-servers/tomcat          *< 5.5.34                 *>= 6.0.35
                                 *< 6.0.35                  >= 7.0.23
                                  < 7.0.23

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

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

Impact
======

The vulnerabilities allow an attacker to cause a Denial of Service, to
hijack a session, to bypass authentication, to inject webscript, to
enumerate valid usernames, to read, modify and overwrite arbitrary
files, to bypass intended access restrictions, to delete work-directory
files, to discover the server's hostname or IP, to bypass read
permissions for files or HTTP headers, to read or write files outside
of the intended working directory, and to obtain sensitive information
by reading a log file.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Apache Tomcat 6.0.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=www-servers/tomcat-6.0.35"

All Apache Tomcat 7.0.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=www-servers/tomcat-7.0.23"
