Synopsis
========
Two vulnerabilities have been found in mod_wsgi, the worst of which
could result in local privilege escalation.

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

Affected packages
=================
-------------------------------------------------------------------

(CVE-2014-0240)
* A memory leak exists via the "Content-Type" header (CVE-2014-0242)

Impact
