<overview>

<p>Ignoring exceptions that should be dealt with in some way is almost always a bad idea.

The loss of information can lead to hard to debug errors and incomplete log files.

It is even possible that ignoring an exception can cause a security vulnerability.

An empty <code>except</code> block may be an indication that the programmer intended to

handle the exception but never wrote the code to do so.</p>

</overview>

<recommendation>

<p>Ensure all exceptions are handled correctly.</p>

</recommendation>

<example>

<p>In this example the program keeps running with the same privileges if it fails to drop to lower

privileges.</p>
