Security guru Bruce Schneier wonders if the iOS security flaw recently reported was deliberate:

Last October, I speculated on the best ways to go about designing and implementing a software backdoor. I suggested three characteristics of a good backdoor: low chance of discovery, high deniability if discovered, and minimal conspiracy to implement.

The critical iOS vulnerability that Apple patched last week is an excellent example. Look at the code. What caused the vulnerability is a single line of code: a second "goto fail;" statement. Since that statement isn't a conditional, it causes the whole procedure to terminate.

If the Apple auditing system is any good, they would be able to trace this errant goto line not just to the source-code check-in details, but to the specific login that made the change. And they would quickly know whether this was just an error, or a deliberate change by a bad actor. Does anyone know what's going on inside Apple?

Schneier has argued previously that the NSA's biggest mistake was dishonesty. Because we don't know what they're up to, and because they've lied so often about it, people start to believe the worst about technology flaws. This Apple error could have been a stupid programmer error, merge conflict, or something in that category. But we no longer trust Apple to work in our best interests.

This is a sad state of affairs.
