Synopsis
=======
A vulnerability in mod_wsgi could lead to privilege escalation.

Background
=========
mod_wsgi is an Apache2 module for running Python WSGI applications.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  www-apache/mod_wsgi          < 4.3.0                    >= 4.3.0 

Description
==========
mod_wsgi, when creating a daemon process group, does not properly
handle dropping group privileges.

Impact
=====
Context-dependent attackers could escalate privileges due to the
improper handling of group privileges.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All mod_wsgi users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=www-apache/mod_wsgi-4.3.0"
