An issue was discovered in certain Apple products. iOS before 11.4 is affected. macOS before 10.13.5 is affected. tvOS before 11.4 is affected. watchOS before 4.3.1 is affected. The issue involves pktmnglr_ipfilter_input in com.apple.packet-mangler in the "Kernel" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (integer overflow and stack-based buffer overflow) via a crafted app.

The version of Apple iOS running on the mobile device is prior to 11.4. It is, therefore, affected by multiple vulnerabilities.

The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.5. It is, therefore, affected by multiple vulnerabilities.

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

According to its banner, the version of Apple TV on the remote device is prior to 11.4. It is, therefore, affected by multiple vulnerabilities as described in the HT208850 security advisory.

Note that only 4th and 5th generation models are affected by these vulnerabilities.

The remote host is running Mac OS X 10.11.6 or Mac OS X 10.12.6 and is missing a security update. It is therefore, affected by multiple vulnerabilities.
