Apple AirPort Base Station Firmware before 7.6.7 and 7.7.x before 7.7.7 misparses DNS data, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors.

Multiple buffer overflows in mDNSResponder before 625.41.2 allow remote attackers to read or write to out-of-bounds memory locations via vectors involving the (1) GetValueForIPv4Addr, (2) GetValueForMACAddr, (3) rfc3110_import, or (4) CopyNSEC3ResourceRecord function.

The handle_regservice_request function in mDNSResponder before 625.41.2 allows remote attackers to execute arbitrary code or cause a denial of service (NULL pointer dereference) via unspecified vectors.

Apple AirPort Base Station Firmware before 7.6.4 does not properly handle incorrect frame lengths, which allows remote attackers to cause a denial of service (device crash) by associating with the access point and then sending a short frame.

A null pointer dereference was addressed with improved input validation. This issue is fixed in AirPort Base Station Firmware Update 7.8.1, AirPort Base Station Firmware Update 7.9.1. A remote attacker may be able to cause a system denial of service.

An out-of-bounds read was addressed with improved input validation. This issue is fixed in AirPort Base Station Firmware Update 7.8.1, AirPort Base Station Firmware Update 7.9.1. A remote attacker may be able to leak memory.

Source-routed IPv4 packets were disabled by default. This issue is fixed in AirPort Base Station Firmware Update 7.8.1, AirPort Base Station Firmware Update 7.9.1. Source-routed IPv4 packets may be unexpectedly accepted.

A use after free issue was addressed with improved memory management. This issue is fixed in AirPort Base Station Firmware Update 7.8.1, AirPort Base Station Firmware Update 7.9.1. A remote attacker may be able to cause arbitrary code execution.

The issue was addressed with improved data deletion. This issue is fixed in AirPort Base Station Firmware Update 7.8.1, AirPort Base Station Firmware Update 7.9.1. A base station factory reset may not delete all user information.

A null pointer dereference was addressed with improved input validation. This issue is fixed in AirPort Base Station Firmware Update 7.8.1, AirPort Base Station Firmware Update 7.9.1. A remote attacker may be able to cause arbitrary code execution.

A denial of service issue was addressed with improved memory handling. This issue is fixed in AirPort Base Station Firmware Update 7.8.1, AirPort Base Station Firmware Update 7.9.1. An attacker in a privileged position may be able to perform a denial of service attack.
