Unspecified vulnerability in the network bridge functionality on the Apple Time Capsule, AirPort Extreme Base Station, and AirPort Express Base Station with firmware before 7.5.2 allows remote attackers to cause a denial of service (networking outage) via a crafted DHCP reply.

The Application-Level Gateway (ALG) on the Apple Time Capsule, AirPort Extreme Base Station, and AirPort Express Base Station with firmware before 7.5.2 modifies PORT commands in incoming FTP traffic, which allows remote attackers to use the device's IP address for arbitrary intranet TCP traffic by leveraging write access to an intranet FTP server.

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.

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 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.
