Mandriva Linux Security Advisory 2014-137

Mandriva Linux Security Advisory 2014-137 - Multiple vulnerabilities have been discovered and corrected in apache-mod_wsgi. 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. 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. The updated packages have been patched to correct these issues.

Red Hat Security Advisory 2014-0788-01

Red Hat Security Advisory 2014-0788-01 - 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. 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.
