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.

Measuring Security IT Success
-----------------------------
In a time where budgets are constrained and Internet threats are on the
rise, it is important for organizations to invest in network security
applications that will not only provide them with powerful
functionality but also a rapid return on investment.

Buffer Overflow Basics
----------------------
A buffer overflow occurs when a program or process tries to store more
data in a temporary data storage area than it was intended to hold.
Since buffers are created to contain a finite amount of data, the extra
information can overflow into adjacent buffers, corrupting or
overwriting the valid data held in them.
