iOS 10.3.2, which Apple released in mid-May, patches seven AVEVideoEncoder vulnerabilities and one IOSurface flaw discovered by Adam Donenfeld of mobile security firm Zimperium. The security holes, which Apple says can be used by an application to gain kernel privileges, are believed to affect all prior versions of the iOS operating system.

The vulnerabilities are tracked as CVE-2017-6979, CVE-2017-6989, CVE-2017-6994, CVE-2017-6995, CVE-2017-6996, CVE-2017-6997, CVE-2017-6998 and CVE-2017-6999. The bugs were discovered between January 24 and March 20, when they were reported to Apple.

Donenfeld, who disclosed his findings this week at the Hack in the Box security conference in Singapore, said he identified the vulnerabilities while analyzing iOS kernel modules. His analysis led to a little-known module, called AppleAVE, which appeared to lack basic security.

Donenfeld demonstrated how some of the flaws in AppleAVE and IOSurface, which can lead to denial-of-service (DoS), information disclosure and privilege escalation, can be chained to achieve arbitrary read/write and root access. The exploit is said to bypass all iOS security mitigations.

"These vulnerabilities would allow elevation of privileges which ultimately can be used by the attacker to take complete control over affected devices," the researcher said in a blog post.

We really need to standardize TLA definitions. PoC confused me for about half a second in the original headline [Ed: changed it to avoid further confusion here].

    TLA confused me for about a half a second in the original summary.

      TFS uses TFA's TLA for PoC, iOS, Mid and May.

        Female announcer: No, the white zone is for loading of passengers and there is no stopping in a RED zone.
        Male announcer: The red zone has always been for loading and unloading of passengers. There's never stopping in a white zone.
        Female announcer: Don't you tell me which zone is for loading, and which zone is for stopping!
        Male announcer: Listen Betty, don't start up with your white zone shit again.
        [Later]
        Male announcer: There's just no stopping in a white zone.
        Female announcer: Oh really, Vernon? Why pretend, we both know perfectly well what this is about. You want me to have an abortion.
        Male announcer: It's really the only sensible thing to do, if its done safely. Therapeutically there's no danger involved.

    I've been wanting to un-cripple my 5C for a long time. The highest exploitable version for this phone is 9.something. Get ssh running and make some much needed changes.

    These exploits are needed to get a Linux boot loader running on the phone. From there, we can get Android up and running.
