We all know the importance of keeping on top of security updates, but there is one kind that might escape your attention if you don’t have it set to check automatically: those for your AirPort base station. Whether you have an AirPort Express, Extreme or Time Capsule, they all have firmware updates to plug security holes and fix other issues.
Apple last month issued an urgent update to the firmware for all AirPort devices to fix a serious flaw.
Impact: A remote attacker may be able to cause arbitrary code execution
Description: A memory corruption issue existed in DNS data parsing. This issue was addressed through improved bounds checking.
But if you don’t have AirPort Utility set to automatically check for updates, you wouldn’t know about it unless you happened to open the app.
You can do this by opening Airport Utility and then Preferences. Ensure that all the boxes are checked, and that the check is set to Daily for maximum protection or Weekly otherwise.
That way, you’ll be automatically alerted if an update is available.
