These guys are the best experts in the world and Apple is getting free work done. Who cares if Apple is angry, Google made their software slightly safer and probably put the iMessage dev team on their toes (as they should be).
Apple carefully controls its messaging to its customers. With Google able to disclose software security flaws, and Apple not able to keep up in fixing them (some non-trivial), it puts some control into the hands of Google.
Doesn't the article say that 5/6 were fixed? And that the 6th isn't disclosed yet, as the 90 day period isn't up yet? Seems like Apple is keeping up reasonably well, wrt disclosure windows.
That doesn’t mean they aren’t upset. Two years ago I spoke with someone on the CoreOS team at a conference and he expressed dissatisfaction at Project Zero. It forces them to halt other work they are doing to design fixes for these bugs, as they often get pressure from Google close to the 90-day window. One fix, he explained, related to process management and would affect all OS builds. Getting that fix integrated and tested into all recent macOS and iOS versions takes time, despite the 90-day window.
The big headlines about vulnerabilities in iMessage being misunderstood by laypeople?
