Apple Fixes iOS Lock Bypass

Apple's iOS 6.1.3 update addresses a screen lock flaw and improves Maps for Japan.

Having recently updated its desktop operating system, OS X, Apple is doing the same for its iOS mobile operating system.

The company on Tuesday released iOS 6.1.3. The update weighs in at a mere 18.2 MB. It can be downloaded directly to an iOS device from the Settings/General/Software Update menu or through iTunes. It is mainly intended to fix a security flaw that made it possible to bypass the passcode screen.

Exploiting the flaw requires some manual dexterity and a call made to emergency services (911) that's immediately cancelled -- perhaps not the best number for a law breaker to call. Doing so provides access to the device's contacts, voicemail and photos, but not to the rest of the apps on the device. However, anyone able to try this exploit presumably has control of the device in question and could employ other tools that can access data on mobile devices, locked or not.

There may be other security fixes as well, but Apple has been slow to update its security updates page, through which it distributes security patch information.

Several hours after iOS 6.1.3 was released, while this story was being written, Apple finally published a link pointing to information about the security content of the update. But the link -- http://support.apple.com/kb/HT5701 -- did not point to any published content. Shortly thereafter, the broken link was removed. It's likely that by the time this article is published, Apple will have repaired the broken link.

The update also includes improvements to Apple's Maps app for Japan. Apple has been improving its cartographic data more broadly since it revised its Maps app (and was roundly criticized for it) last September. Last month, the company expanded its effort to hire engineers to improve Maps.

A link to a new Apple TV update, Apple TV 5.2.1, was also removed from Apple's security updates page, though the linked page continues to be accessible. It describes fixes for three security flaws affecting Apple TV units: CVE-2013-0977, CVE-2013-0978 and CVE-2013-0981.

The first involves a state management flaw that has to do with the way Mach-O executable files with overlapping segments are handled, a vulnerability that could be exploited to allow unsigned code. The second involves an information disclosure flaw in the ARM prefetch abort handler that could allow a local user to access the address of structures in the kernel. The third involves an IOUSBDeviceFamily driver that didn't adequately validate pipe object pointers, allowing the possibility of arbitrary code execution.

re: Apple Fixes iOS Lock Bypass
It is kind of funny when you think about it, a simple bypass to unlock the phone and have access to their phones data. It is even more funny when that phone is leading the mobile device pack.These seem to cover just about any user, all the programs are pretty common which makes the number of people susceptible much higher. It is a good thing Apple addressed these issues but should they even have been issues to begin with?

Well, you have to give props to Apple for at least doing a very quick fix.

Enterprise Vulnerabilities
From DHS/US-CERT's National Vulnerability Database
CVE-2014-4448
Published: 2014-10-22
House Arrest in Apple iOS before 8.1 relies on the hardware UID for its encryption key, which makes it easier for physically proximate attackers to obtain sensitive information from a Documents directory by obtaining this UID.

CVE-2014-4449
Published: 2014-10-22
iCloud Data Access in Apple iOS before 8.1 does not verify X.509 certificates from TLS servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

CVE-2014-4450
Published: 2014-10-22
The QuickType feature in the Keyboards subsystem in Apple iOS before 8.1 collects typing-prediction data from fields with an off autocomplete attribute, which makes it easier for attackers to discover credentials by reading credential values within unintended DOM input elements.

CVE-2012-5242
Published: 2014-10-21
Directory traversal vulnerability in functions/suggest.php in Banana Dance B.2.6 and earlier allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the name parameter in a get_template action.

CVE-2012-5243
Published: 2014-10-21
functions/suggest.php in Banana Dance B.2.6 and earlier allows remote attackers to read arbitrary database information via a crafted request.
