The result of my Black Hat presentation on the current protection measures in place in current linux boxes would be that systems are overall very secure as NX/DEP is deployed in every process without any exceptions, ASLR is in place by default and Stack Canary values additionaly add to security.
However, there are still some flaws that are yet to be fixed:

Auch wenn die Verhandlungen über ein Semesterticket in München wieder aufgenommen wurden, sind Ergebnisse nach dem plötzlichen Abbruch der Verhandlungen im letzten Jahr noch in weiter ferne. Grund genug also, das Pilotprojekt SemesterTicketGeneratR zu verlängern und für das Sommersemester 2009 zu rüsten.

You know, it really sucks when you log into a machine and for some reason there is a delay before the connection is fully functional. This happend to the SSH of a server to which I frequently connect, delaying my connections for 8 to 30 seconds. Again it sucked, up to a degree where I decided to track down the issue and fix it. Google told me, it’s reverse DNS mappings and I should set UseDNS no in the sshd_config, but that didn’t work (and besides, reverse DNS can’t be that slow…). Read More...
