Insight
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.
