Thank you for reading the Linux Advisory Watch Security Newsletter. The
purpose of this document is to provide our readers with a quick summary of
each week's vendor security bulletins and pointers on methods to improve
the security posture of your open source system.
Vulnerabilities affect nearly every vendor virtually every week, so be
sure to read through to find the updates your distributor have made
available.

Using password guessing as an attack vector. Over the years we've been

secure. Some of us have taken that notion to heart and always ensure
our passwords are strong. But some don't give a second thought to the
complexity or length of our password.
