Combo Update is here:
https://support.apple.com/kb/DL1832?locale=en_US

Does anyone know yet if the issue released here is addressed in this version? I had heard that the latest betas of 10.10.5 fixed the issue, but I haven't installed this yet to see. Wondering if anyone has already done the work of testing and can confirm/deny any fixing, etc.

If this does plug this very serious issue, I think we'll be fast tracking this update into production and Self Service pretty quickly.

@mm2270 Yep, that's definitely fixed in the release.

Awesome! Thanks for the quick confirmation @RobertHammen Time to test and get prepped then!

Well.......

So... what is meant exactly by his tweet? Everything I've read so far indicates this was patched in 10.10.5. Is Stefan just spreading FUD here or is there still a legitimate concern? I just looked at his Twitter feed and all I see are cryptic posts like the one above, no real indication of anything substantial. I have not been able to find any posts/evidence yet that this update doesn't actually fix the issue, or if it introduces extra issues.

I tested against it this morning, and definitely seems to be fixed in our ENV

"Hmm, so Apple released 10.10.5 fixed some bugs and made another security problem worse than before"

Sounds like there's another vulnerability. Pretty unlikely Apple releases another dot release of 10.10, so we may see a Security Update 2015-001 for Yosemite if this is deemed to be critical.
