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
=================

-------------------------------------------------------------------

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

handle dropping group privileges.

Impact

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

Workaround

Resolution
