Linux Advisory Watch 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.

Password guessing as an attack vector - Using password guessing as an attack vector. Over the years we've been taught a strong password must be long and complex to be considered secure.
