I’m sorry for the long absence, but last three months has been really intense.
Probably you know yet about Heartbleed, the bug in the most used SSL library.
Another very huge bug has been discovered in this days, Shellrock. This bug is present in Bash, the shell utility more used in the world in almost all unix/linux devices. Bash is used in Router, Server, Macs ad so on… Actually the patch has been released and all the major Linux distribution have already patched Bash. The bug is already exploited, infacts it’s easily exploitable through special http request to services using bash.
The problem is this bug has present for many years in bash, therefore there will be vulnerable systems for more years.
It’s recommended to upgrade immediately all linux systems.
