Today, Jeff release his OS Desktop vulnerability report for H1 2008, which shows to me some interesting results.

One is if you look at the Days of Risk – say on average after disclosure how many days did it take a vendor to fix a vulnerability. He weighted them as well based on whether they are critical or important or low:

Secondly he shows the number of vulnerabilities of all the vendors he is looking at:

And last but definitely not least he compares the different OSs:

There is one other interesting finding: 25% of the vulnerabilities are shared by more than one vendor!

So, if you want to download the report, here you find Jeff's post:


  • The 25% shared stat is the most interesting for me. To be honest, in my opinion 90% of any OS's security problems sits behind the keyboard. Like most, Windows gives the user more than enough instruments to be save.

  • It is as so often, autumn is the time when all the big events are happening in EMEA. This week was RSA
