there is an issue with flash security (again) that will
send our computers straight to Steve Jobs begging for HTML5 browser
support. Meanwhile, Jobs sits back with a smirk as he watches his
plan unfold. But seriously, this issue was stated to be a problem for
10.X and 9.X versions up to 10.0.45.2 and earlier. Versions 8.X is
safe, and the recommended course of action is to upgrade to the
current release candidate if at risk. I think I'll just wait for a
patch and not click on any flash-block icons for a bit.

Sounds a lot like the issue they had in June of last year, only they
are not including Adobe Air in the mix this time.
