Description


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 RĂ³bert 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.
