Oracle Linux 7 : mod_wsgi (ELSA-2014-1091)

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2014:1091 :

An updated mod_wsgi package that fixes one security issue is now
available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link 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.

Red Hat would like to thank Graham Dumpleton for reporting this issue.
Upstream acknowledges Robert Kisteleki as the original reporter.

All mod_wsgi users are advised to upgrade to this updated package,
which contains a backported patch to correct this issue.
