Bugzilla, Mozilla's free and popular bug tracking program, has just been updated to patch a number of security holes.
One of them is not only interesting and important, but also ironic.
In fact, if we are allowed to smile at security holes, this bug is wryly amusing.
Many Bugzilla implementations are publicly accessible on the internet, as a way of encouraging anyone who's interested in helping out with bug fixing.
Open and closed source projects alike use Bugzilla for just this purpose.
If you make it easy for your users to give you feedback about things that aren't working properly, you can build an engaged online community and improve your software engineering at the same time.
