Description Murray McAllister 2014-06-19 06:11:02 UTC
mod_wsgi allows you to host Python applications on the Apache HTTP Server. It was reported that mod_wsgi failed to handle errors when attempting to drop group privileges. An error would be printed, but mod_wsgi would continue running with root group privileges.

If an administrator has configured mod_wsgi to allow less trusted users to run a WSGI application, they could use this flaw to escalate their privileges if a group-dropping function failed.

This issue has been fixed in the 4.2.4 release:
