While I have been involved in the triaging/patch creation for most CVE's(for Maverick) discussed here, this is one that I picked up because of sheer curiosity. I was not involved in triaging or bugfixing it. The fix was provided by Leo Iannacone.
Lets start off here; we can notice that versions after Maverick are affected. There is not much to explore as most of it has been discussed on various mailing lists and forums already; it seems like a case of a straightforward heap overflow to me.
