Google's 'Project Zero' Hid A Major Vulnerability in Apple's OS and iOS Cores (thestack.com)
In June Google's task-force against zero day exploits "identified a coding exploit in the underlying kernel of Apple's OSX and it's mobile operating system iOS, which could allow for root-level escalation of privileges for an attacker in a non-updated version of the OS," according to The Stack.
An anonymous reader writes that Google "initially refused Apple's request for sixty days' grace, but eventually settled on September 21st for disclosure. But when Apple's last-minute September fix turned out to be ineffective, Project Zero agreed to keep quiet, eventually granting Apple nearly five months of silence about the task_t bug -- which has now been fixed in the latest updates to Mac OS and iOS." The fix was released Monday, the Stack reports: Since the task_t bug allows the user to gain any entitlements they may want, it could also nullify kernel code signing, which would allow unauthorized programs to run with elevated privileges on a Mac system. Any current OSX or iOS user who has applied the latest system updates is not susceptible to the task_t vulnerability.

Isn't the point of eventual disclosure to force coders/companies not to ignore bugs?
Yes, Google found a bug. But Apple didn't ignore it - their initial patch just wasn't effective. They were obviously actively working to solve the problem... so why should Google have released the exploit?

Using the words "hid a major vulnerability" is misleading. It implies Google infiltrated Apple source code to implant an exploit. Google didn't hide shit. They found the exploit, informed Apple, and kept quiet about it for the safety of the users.
