The FTP proxy server in Apple AirPort Express, AirPort Extreme, and Time Capsule with firmware 7.5 does not restrict the IP address and port specified in a PORT command from a client, which allows remote attackers to leverage intranet FTP servers for arbitrary TCP forwarding via a crafted PORT command.

Apple Airport Extreme firmware 0.1.27 in Mac OS X 10.4.8 on Mac mini, MacBook, and MacBook Pro with Core Duo hardware allows remote attackers to cause a denial of service (out-of-bounds memory access and kernel panic) and have possibly other security-related impact via certain beacon frames.

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.

fsck, as used by the AirPort Disk feature of the AirPort Extreme Base Station with 802.11n before Firmware Update 7.1, and by Apple Mac OS X 10.3.9 through 10.4.9, does not properly enforce password protection of a USB hard drive, which allows context-dependent attackers to list arbitrary directories or execute arbitrary code, resulting from memory corruption.

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.
