Amazon Linux 1 Security Advisory: ALAS-2014-376
Advisory Release Date: 2014-07-09 23:07 Pacific
Advisory Updated Date: 2014-09-19 10:18 Pacific
Severity: Important

Issue Overview:

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.

mod_wsgi allows you to host Python applications on the Apache HTTP Server. It was found that a remote attacker could leak portions of a mod_wsgi application's memory via the Content-Type header.
