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"
