  • Address bar spoofing
  • Multiple memory corruption issues
  • Arbitrary code execution on the Wi-Fi chip

This last one for the Wi-Fi chip can allow attackers in Wi-Fi range to find and take over you device and crash it. This exploit is known as Broadpwn and has been given a 9.8/10 score US’s National Institute of Standards and Technology severity scale (NIST). It’s not just an Apple problem, mobile devices with the Broadcom chip-set are likely to be at risk, Google has already patched it’s devices.
