USN-2431-1: mod_wsgi vulnerability

3 December 2014

mod_wsgi could be made to run programs with incorrect privileges.



  • mod-wsgi - Python WSGI adapter module for Apache


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

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04

After a standard system update you need to restart your web service to make
all the necessary changes.
