9.0.124 fixed a very serious zero-day security vulnerability present in previous versions of Flash Player. Unfortunately 9.0.124 broke h.264/AAC streaming from Adobe servers using specific protocols.
Which would I rather not have, hmmm... h.264/AAC streaming from some servers to my mobile device, or device Pwnage? Yeah, the ability to stream a few videos that may not actually be playable is really worth having my device compromised.
