The network interface for Apple AirPort Express 6.x before Firmware Update 6.3, and AirPort Extreme 5.x before Firmware Update 5.7, allows remote attackers to cause a denial of service (unresponsive interface) via malformed packets.

Apple AirPort Express prior to 6.1.1 and Extreme prior to 5.5.1, configured as a Wireless Data Service (WDS), allows remote attackers to cause a denial of service (device freeze) by connecting to UDP port 161 and before link-state change occurs.

The ICMPv6 implementation on the Apple Time Capsule, AirPort Extreme Base Station, and AirPort Express Base Station with firmware before 7.5.2 does not limit the rate of (1) Router Advertisement and (2) Neighbor Discovery packets, which allows remote attackers to cause a denial of service (resource consumption and device restart) by sending many packets.
