You may not take even a second to respond. But if I may ask "How much does Google know about you"? You may instantly reply "Wait... what!? Do they!?" The book "Googling Security: How Much Does Google Know About You" by Greg Conti (Computer Science Professor at West Point) is the first book to reveal how Google's vast information stockpiles could be used against you or your business and what you can do to protect yourself. http://www.linuxsecurity.com/content/view/145939 --- A Secure Nagios Server ---------------------- Nagios is a monitoring software designed to let you know about problems on your hosts and networks quickly. You can configure it to be used on any network. Setting up a Nagios server on any Linux distribution is a very quick process however to make it a secure setup it takes some work. This article will not show you how to install Nagios since there are tons of them out there but it will show you in detail ways to improve your Nagios security. http://www.linuxsecurity.com/content/view/144088 --> Take advantage of the LinuxSecurity.com Quick Reference Card! <-- --> http://www.linuxsecurity.com/docs/QuickRefCard.pdf <-- ------------------------------------------------------------------------ * EnGarde Secure Community 3.0.22 Now Available!

A wrong handling of that variable enables local attackers to execute arbitrary code via Python scripting in the current dia working directory (CVE-2008-5984). This update provides fix for that vulnerability. http://www.linuxsecurity.com/content/view/148013 * Mandriva: [ MDVSA-2009:039 ] gedit (Feb 16) ------------------------------------------- Python has a variable called sys.path that contains all paths where Python loads modules by using import scripting procedure. A wrong handling of that variable enables local attackers to execute arbitrary code via Python scripting in the current gedit working directory (CVE-2009-0314). This update provides fix for that vulnerability. http://www.linuxsecurity.com/content/view/148012 * Mandriva: [ MDVSA-2009:038 ] blender (Feb 16) --------------------------------------------- Python has a variable called sys.path that contains all paths where Python loads modules by using import scripting procedure.

In this particular case the DSA_verify function was fixed with MDVSA-2009:002, this update does however address the RSA_verify function (CVE-2009-0265). http://www.linuxsecurity.com/content/view/148010 * Mandriva: [ MDVSA-2009:036 ] python (Feb 12) -------------------------------------------- Multiple integer overflows in imageop.c in the imageop module in Python 1.5.2 through 2.5.1 allow context-dependent attackers to break out of the Python VM and execute arbitrary code via large integer values in certain arguments to the crop function, leading to a buffer overflow, a different vulnerability than CVE-2007-4965 and CVE-2008-1679. (CVE-2008-4864) http://www.linuxsecurity.com/content/view/147981 * Mandriva: [ MDVA-2009:023 ] db46 (Feb 12) ----------------------------------------- Additional official patches have been released for db 4.6 after Mandriva release. http://www.linuxsecurity.com/content/view/147979 * Mandriva: [ MDVA-2009:022 ] xkeyboard-config (Feb 12) ----------------------------------------------------- Wrong directory permissions would prevent the compilation of keyboard mappings.
