Flaws in the iOS kernel, WebKit and Passbook addressed
Apple has released iOS 6.0.1 which fixes a host of security vulnerabilities from the initial release of iOS 6.
There were four flaws that required patching, one of which is an issue in the iOS kernel, which could have allowed “maliciously crafted or compromised iOS applications” to determine addresses in the kernel, Apple noted in its advisory.
Two of the issues were resident in WebKit, the basis of the Safari browser in iOS, which opened up users to remote code execution if they visited a maliciously crafted website.
Pinkie Pie, the sole winner of Google’s Pwnium 2 contest in October, discovered one of those flaws, whilst the other was found by Joost Pol and Daan Keuper of Certified Secure working with the HP Zero Day Initiative.
There was also a Passcode bypass flaw, which could have allowed hackers to gain access to the Passbook app, which lets users store passes for things such as flights or cinema tickets. The vulnerability would have let a determined cyber crook break into the app even when a device is locked.
“We recommend updating your software as soon as possible, as both updates contain critical vulnerabilities that allow an attacker to take control of your systems,” said Wolfgang Kandek, CTO of Qualys.
As these updates highlight, iOS is far from 100 percent secure. When iOS 6 was first released, it fixed 197 flaws.
