Apple Macs, iPhones, iPads, Watches, TVs can be hijacked by evil Wi-Fi, PDFs – update now

iOS, OS X, watchOS, tvOS all patched

Updated Apple has today emitted security updates for pretty much everything it makes, and you should install them as soon as you can because it's all bad news.

iPhones, iPads and iPods should grab iOS 9.3, Macs should fetch OS X 10.11.4 or Security Update 2016-002 for non-El Capitan Macs, Apple Watches should get watchOS 2.2, and Apple TVs should install tvOS 9.2. Your hardware should eventually offer the updates to you automatically, or you can follow these instructions to get going right away.

As well as fixing the iMessage decryption flaw that we were warned about on Sunday, the new software also closes bugs that allow malicious Wi-Fi networks, PDF files, fonts and more to execute malware on devices and computers.

Opening a booby-trapped file, or connecting to a dodgy wireless network, could lead to your computer or handheld being hijacked to spy on you, steal your passwords, and so on. In this latest round of patches, there's a heady mix of remote code execution flaws, code signing bypasses, escalations to kernel mode, and kernel memory map leaks, which can be chained together to fully compromise Apple gear.

Here are all the bugs found and fixed in iOS and OS X, which need to be squashed on your systems and gadgets before miscreants start exploiting them in the wild:

iOS

Grab iOS 9.3 to fix...

  • CVE-2016-1734 in AppleUSBNetworking: An application may be able to execute arbitrary code with kernel privileges by exploiting a memory corruption bug in the parsing of data from USB devices.
  • CVE-2016-1740 in FontParser: Opening a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution.
  • CVE-2015-8659 in HTTPProtocol: A remote attacker may be able to execute arbitrary code by exploiting a bug in Nghttp2.
  • CVE-2016-0801 and CVE-2016-0802 in Wi-Fi: An attacker with a privileged network position may be able to execute arbitrary code, thanks to a frame validation and memory corruption issue for a given ethertype.
  • CVE-2016-1752 in Kernel: An application may be able to cause a denial of service. Found by GCHQ's bug hunters CESG.
  • CVE-2016-1750 in Kernel: An application may be able to execute arbitrary code with kernel privileges. Also found by CESG.
  • CVE-2016-1753 in Kernel: An application may be able to execute arbitrary code with kernel privileges.
  • CVE-2016-1751 in Kernel: An application may be able to bypass code signing, ie: untrusted malware can exploit this bug to run within Apple's walled garden.
  • CVE-2016-1757 in Kernel: An application may be able to execute arbitrary code with kernel privileges by exploiting a race condition existed during the creation of new processes.
  • CVE-2016-1756 in Kernel: An application may be able to execute arbitrary code with kernel privileges by exploiting a null pointer dereference.
  • CVE-2016-1754 and CVE-2016-1755 in Kernel: An application may be able to execute arbitrary code with kernel privileges.
  • CVE-2016-1758 in Kernel: An application may be able to determine kernel memory layout.

A cryptographic issue was addressed by rejecting duplicate messages on the client. This is the scary flaw highlighted over the weekend; it is by far not the worst bug here. You need to be able to impersonate a root CA to pull it off.
  • CVE-2016-1766 in Profiles: An untrusted MDM profile may be incorrectly displayed as verified.
  • CVE-2016-1950 in Security: Processing a maliciously crafted certificate may lead to arbitrary code execution. A memory corruption issue existed in the ASN.1 decoder, surprise, surprise.

OS X

Updates are now available to install for OS X Mavericks 10.9, OS X Yosemite 10.10, and OS X El Capitan 10.11. A number of the following bugs are fixed only in El Capitan for reasons best understood by Apple; in general, it's strongly advised that you use Apple's latest operating system releases as these tend to comprehensively patched.
