+----------------------------------------------------------------------+ | LinuxSecurity.com Linux Advisory Watch | | January 27th, 2012 Volume 13, Number 4 | | | | Editorial Team: Dave Wreski <dwreski@xxxxxxxxxxxxxxxxx> | +----------------------------------------------------------------------+ 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. 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. http://www.linuxsecurity.com/content/view/156412 ------------------------------------------------------------------------ * Debian: 2394-1: libxml2: Multiple vulnerabilities (Jan 26) ---------------------------------------------------------- Many security problems had been fixed in libxml2, a popular library to handle XML data files.
