Description Trevor Jay 2014-03-14 02:10:41 EDT
Dominic Cleal of Red Hat reports:

The kafo_configure puppet module creates /tmp/default_values.yaml world readable and without checking for it's existance. This creates a race-condition that would allow a local attacker to control the contents of the file which stores default values for all parameters (such as auto-generated passwords).
