mod-wsgi vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

mod_wsgi could be made to run programs with incorrect privileges.

Software Description:
- mod-wsgi: Python WSGI adapter module for Apache

Details:

It was discovered that mod_wsgi incorrectly handled errors when setting up
the working directory and group access rights. A malicious application
could possibly use this issue to cause a local privilege escalation when
using daemon mode.

Update instructions:

package versions:

Ubuntu 14.10:

  libapache2-mod-wsgi             3.3-4ubuntu0.2
  libapache2-mod-wsgi-py3         3.3-4ubuntu0.2
