PHP 4.3.9 exploit?

We are currently on the Stable/Manual update preference. Cpanel is showing php 4.3.9 running . What should we do at this stage? I've poked around and run some searches on the forums, but everything looks like a different issue (mod_security or a phpbb exploit). What's the current solution for the 4.3.9 php vulnerability? I've seen a lot of posts talking about problems w/ 4.3.10 and we are loathe to go that route until all issues are resolved. Any advice?

Haven't had any problems with 4.3.10 so long as you upgrade zend optimizer to 2.5.7 if you already have it installed.

Edit: On at least 15 servers so far
