Lots Of Recent Apple Security Patches

--

While I was taking a break to get over a cold, Apple has provided lots of new security patches. Here is my summary:

 I) Security Update 2013-001
(For Snow Leopard, Snow Leopard Server, Lion and Lion Server, included in OS X Mountain Lion Update 10.8.3)

Apple's security content document:

II) OS X Mountain Lion Update 10.8.3
(Update and Combo Update)

Apple's security content document (same as above):

About the security content of OS X Mountain Lion v10.8.3 and Security Update 2013-001

The security patch content is the generally same as Security Update 2013-001 and Safari 6.0.3.

III) Safari v6.0.3
(Included as part of OS X 10.8.3 and Security Update 2013-001)

Apple's security content document:

CVE-2013-0961 - A maliciously crafted website could cause unexpected application termination or arbitrary code execution, aka bad memory management.

CVE-2012-2889 - A maliciously crafted website could use frame elements to allow a cross-site scripting attack.

CVE-2013-0962 - Pasting content on a malicious website could allow a cross-site scripting attack.

IV) iOS 6.1.3

Apple's security content document:

About the security content of iOS 6.1.3

AHEM: Before I get into what this version of iOS fixes, I have to point out that iOS 6.1.3 allows yet-another passcode lock bypass. Sigh. This one enables anyone to use the phone for calls and provides access to the owner's photo gallery. That is all. But that is enough! Read about it and watch the break-in demonstration video at Sophos:

iOS 6.1.3 security flaw allows passcode lock bypass... again [VIDEO]

Summary: This update patched the screen lock bypass problem accessible via making an emergency call. The other five patches cover a variety of issues in WebKit, dyld, lockdownd, USB and the Kernel.

CVE-IDs:

CVE-2013-0912 - A maliciously crafted website could use SVG files to cause unexpected application termination or arbitrary code execution; Affects WebKit.

CVE-2013-0977 - Unsigned code could be executed could result from incorrect handling of Mach-O executable files with overlapping segments; Affects dyld.

CVE-2013-0978 - The addresses of structures in the kernel were disclosed via an issue in the ARM prefetch abort handler; Affects Kernel.

CVE-2013-0979 - Able to change permissions on arbitrary files that included a symbolic link after restoring from a backup; Affects LockDown / lockdownd.

CVE-2013-0980 - Screen lock bypass via a logic error in the handling of emergency calls form the lock screen; Affects Passcode Lock.

CVE-2013-0981 - Execution of arbitrary code via an issue with pipe object pointers in the IOUSBDeviceFamily driver; Affects USB.


V) Apple TV v5.2.1

Apple's security content document:
About the security content of Apple TV 5.2.1

Summary: The three patched security flaws are, not surprisingly, also found in iOS 6.1.3.

CVE-IDs:

CVE-2013-0977 - - Unsigned code could be executed could result from incorrect handling of Mach-O executable files with overlapping segments.

CVE-2013-0978 - The addresses of structures in the kernel were disclosed via an issue in the ARM prefetch abort handler.

CVE-2013-0981 - Execution of arbitrary code via an issue with pipe object pointers in the IOUSBDeviceFamily driver.


General Conclusion: As I often say, bad memory management is the bane of modern coding. However, it's interesting to see a wide variety of issues addressed in these updates, not just memory management. Hopefully, this indicates few memory management problems remain in Apple's software, causing attention to turn to other aspects of Apple code.
