Broni--The first page of the Secunia link you provided really did not say too much. I clicked on the 2008 advisories and could not find reference to the versions of Flash that are vulnerable. Do you have a link for that?
I ran Secunia's Online Software Inspector scan. It said 9.0.124.0 (on my PC) is OK.
I wonder if there is some confusion with the April vulnerability announcement from Adobe, where they suggest updating to 9.0.124.0http://www.adobe.com/support/security/bulletins/apsb08-11.html
However PSI did say that my Macromedia Flash Player (v 6.0.79.0) is "insecure" and should be updated to v 6.0.88.0.
