Multiple memory corruption issues were addressed with improved memory handling. This issue affected versions prior to iOS 12.1.1, tvOS 12.1.1, watchOS 5.1.2, Safari 12.0.2, iTunes 12.9.2 for Windows, iCloud for Windows 7.9.

The version of Apple iOS running on the mobile device is prior to 12.1.1. It is, therefore, affected by multiple vulnerabilities. The highest of which could allow an attacker to perform a remote code execution attack by enticing a user to view malicious web content.

The version of Apple Safari installed on the remote host is prior to 12.0.2. It is, therefore, affected by the following vulnerabilities :

 - Input-validation errors exist that allow memory corruption leading to arbitrary code execution. (CVE-2018-4437, CVE-2018-4438, CVE-2018-4441, CVE-2018-4442, CVE-2018-4443, CVE-2018-4464)

Note that other flaws exist that allow information disclosure and address bar spoofing.

According to its banner, the version of Apple TV on the remote device is prior to 12.1.1. It is, therefore, affected by multiple vulnerabilities as described in the HT209342 security advisory:

  - Multiple elevation of privilege vulnerabilities exist due to     improper memory handling. An application can exploit this to gain     elevated privileges. (CVE-2018-4303, CVE-2018-4435)

  - Multiple unspecified command execution vulnerabilities exist that     allow an attacker to execute arbitrary commands, sometimes with     kernel privileges. (CVE-2018-4427, CVE-2018-4437, CVE-2018-4438,     CVE-2018-4447, CVE-2018-4461, CVE-2018-4464, CVE-2018-4441,     CVE-2018-4442, CVE-2018-4443)

  - 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-2018-4460)

Additionally, the version of Apple TV is also affected by several additional vulnerabilities including cross-site scripting (XSS) and an information disclosure vulnerability.

Note that only 4th generation devices are affected by these vulnerabilities.

The version of Apple iTunes installed on the remote Windows host is prior to 12.9.2. It is, therefore, affected by multiple vulnerabilities as referenced in the HT209345 advisory.

  - Visiting a malicious website may lead to address bar spoofing     (CVE-2018-4440)

  - Visiting a malicious website may lead to user interface spoofing     (CVE-2018-4439)

  - Processing maliciously crafted web content may lead to arbitrary     code execution. (CVE-2018-4437, CVE-2018-4464)

  - Processing maliciously crafted web content may lead to arbitrary     code execution. (CVE-2018-4441, CVE-2018-4442, CVE-2018-4443)

  - Processing maliciously crafted web content may lead to arbitrary     code execution. (CVE-2018-4438)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Apple iOS running on the mobile device is prior to 12.1. It is, therefore, affected by multiple vulnerabilities. The highest of which could allow an attacker to perform a remote code execution attack by enticing a user to view malicious web content.

The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 12.0.2. It is, therefore, affected by the following vulnerabilities :

  - Input-validation errors exist that allow memory     corruption leading to arbitrary code execution.
    (CVE-2018-4437, CVE-2018-4438, CVE-2018-4441,     CVE-2018-4442, CVE-2018-4443, CVE-2018-4464)

Note that other flaws exist that allow information disclosure and address bar spoofing.
