An updated mod_wsgi package that fixes two security issues is now available
for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
Important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

The mod_wsgi adapter is an Apache module that provides a WSGI-compliant
interface for hosting Python-based web applications within Apache.

It was found that mod_wsgi did not properly drop privileges if the call to
setuid() failed. If mod_wsgi was set up to allow unprivileged users to run
WSGI applications, a local user able to run a WSGI application could
possibly use this flaw to escalate their privileges on the system.

Note: mod_wsgi is not intended to provide privilege separation for WSGI
applications. Systems relying on mod_wsgi to limit or sandbox the
privileges of mod_wsgi applications should migrate to a different solution
with proper privilege separation.

It was discovered that mod_wsgi could leak memory of a hosted web
application via the "Content-Type" header. A remote attacker could possibly
use this flaw to disclose limited portions of the web application's memory.

Red Hat would like to thank Graham Dumpleton for reporting these issues.
Upstream acknowledges RĂ³bert Kisteleki as the original reporter of
CVE-2014-0240, and Buck Golemon as the original reporter of CVE-2014-0242.

All mod_wsgi users are advised to upgrade to this updated package, which
contains backported patches to correct these issues.
