RHEL 6 : mod_wsgi (RHSA-2014:0788)

This script is Copyright (C) 2014-2017 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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. (CVE-2014-0240)

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. (CVE-2014-0242)

Red Hat would like to thank Graham Dumpleton for reporting these
issues. Upstream acknowledges Robert 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.
