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)
