Synopsis
========

A bug in the way Apache handles the Satisfy directive can lead to the
exposure of protected directories to unauthorized users.

Background
==========

The Apache HTTP server is one of most popular web servers on the
Internet.

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

    -------------------------------------------------------------------
     Package         /  Vulnerable  /                       Unaffected
    -------------------------------------------------------------------
  1  net-www/apache      == 2.0.51                        >= 2.0.51-r1
                                                              < 2.0.51

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

A bug in the way Apache handles the Satisfy directive, which is used to
require that certain conditions (client host, client authentication,
etc) be met before access to a certain directory is granted, could
allow the exposure of protected directories to unauthorized clients.

Impact
======

Directories containing protected data could be exposed to all visitors
to the webserver.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Apache users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=net-www/apache-2.0.51-r1"
    # emerge ">=net-www/apache-2.0.51-r1"
