Synopsis
========

Multiple vulnerabilities in Tomcat may lead to local file overwriting,
session hijacking or information disclosure.

Background
==========

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

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

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  www-servers/tomcat      < 6.0.16                       *>= 5.5.26
                                                             >= 6.0.16

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

The following vulnerabilities were reported:

* Delian Krustev discovered that the JULI logging component does not
  properly enforce access restrictions, allowing web application to add
  or overwrite files (CVE-2007-5342).

* When the native APR connector is used, Tomcat does not properly
  handle an empty request to the SSL port, which allows remote
  attackers to trigger handling of a duplicate copy of one of the
  recent requests (CVE-2007-6286).

* If the processing or parameters is interrupted, i.e. by an
  exception, then it is possible for the parameters to be processed as
  part of later request (CVE-2008-0002).

* An absolute path traversal vulnerability exists due to the way that
  WebDAV write requests are handled (CVE-2007-5461).

* Tomcat does not properly handle double quote (") characters or %5C
  (encoded backslash) sequences in a cookie value, which might cause
  sensitive information such as session IDs to be leaked to remote
  attackers and enable session hijacking attacks (CVE-2007-5333).

Impact
======

These vulnerabilities can be exploited by:

* a malicious web application to add or overwrite files with the
  permissions of the user running Tomcat.

* a remote attacker to conduct session hijacking or disclose
  sensitive data.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Tomcat 5.5.x users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-servers/tomcat-5.5.26"

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

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-servers/tomcat-6.0.16"
