A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 12.3, tvOS 12.3, watchOS 5.2.1. An application may be able to execute arbitrary code with system privileges.

The version of Apple tvOS installed on the remote host is greater or equal to 12.0.0 and prior to 12.3. It is, therefore, affected by the following vulnerabilities :

 - An application may be able to execute arbitrary code with system privileges. (CVE-2019-8593)

 - Processing a maliciously crafted movie file may lead to arbitrary code execution. (CVE-2019-8585)

 - A malicious application may be able to read restricted memory. (CVE-2019-8560)

 - A malicious application may be able to execute arbitrary code with system privileges. (CVE-2019-8605)

 - A local user may be able to cause unexpected system termination or read kernel memory. (CVE-2019-8576)

 - An application may be able to cause unexpected system termination or write kernel memory. (CVE-2019-8591)

 - A local user may be able to modify protected parts of the file system. (CVE-2019-8568)

 - A malicious application may be able to gain root privileges. (CVE-2019-8637)

 - An application may be able to gain elevated privileges. (CVE-2019-8577)

 - A maliciously crafted SQL query may lead to arbitrary code execution. (CVE-2019-8600)

 - A malicious application may be able to read restricted memory. (CVE-2019-8598)

 - A malicious application may be able to elevate privileges. (CVE-2019-8602)

 - An application may be able to execute arbitrary code with system privileges. (CVE-2019-8574)

 - Processing maliciously crafted web content may result in the disclosure of process memory. (CVE-2019-8607)

 - Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2019-6237, CVE-2019-8571, CVE-2019-8583, CVE-2019-8584, CVE-2019-8586, CVE-2019-8587, CVE-2019-8594, CVE-2019-8595, CVE-2019-8596, CVE-2019-8597, CVE-2019-8601, CVE-2019-8608, CVE-2019-8609, CVE-2019-8610, CVE-2019-8611, CVE-2019-8615, CVE-2019-8619, CVE-2019-8622, CVE-2019-8623, CVE-2019-8628)

 - A device may be passively tracked by its WiFi MAC address. (CVE-2019-8620)

The version of Apple iOS running on the mobile device is prior to 12.3. It is, therefore, affected by multiple vulnerabilities as described in the HT210118 security advisory.

 - Multiple elevation of privilege vulnerabilities exist due to improper memory handling. An application can exploit this to gain elevated privileges. (CVE-2019-8593, CVE-2019-8605, CVE-2019-8574)

 -Multiple unspecified command execution vulnerabilities exist that allow an attacker to execute arbitrary commands, sometimes with kernel privileges. (CVE-2019-8585, CVE-2019-8613,CVE-2019-8600, CVE-2019-6237, CVE-2019-8571, CVE-2019-8583, CVE-2019-8584, CVE-2019-8586, CVE-2019-8587, CVE-2019-8594, CVE-2019-8595, CVE-2019-8596, CVE-2019-8597, CVE-2019-8601, CVE-2019-8608, CVE-2019-8609, CVE-2019-8610, CVE-2019-8611, CVE-2019-8615, CVE-2019-8619, CVE-2019-8622, CVE-2019-8623, CVE-2019-8628)

 -An unspecified denial of service (DoS) vulnerability exists in the Kernel that allows an an attacker in a privileged position to perform a denial of service attack. (CVE-2019-8626)

According to its banner, the version of Apple TV on the remote device is prior to 12.3. It is therefore affected by multiple vulnerabilities as described in the HT210120 security advisory:

  - Multiple unspecified command execution vulnerabilities exist that     allow an attacker to execute arbitrary commands, sometimes with     kernel privileges.(CVE-2019-8593, CVE-2019-8585, CVE-2019-8605,     CVE-2019-8600, CVE-2019-8574)
