An out-of-bounds read was addressed with improved input validation. This issue is fixed in iOS 12.4, macOS Mojave 10.14.6, tvOS 12.4, watchOS 5.3. Parsing a maliciously crafted office document may lead to an unexpected application termination or arbitrary code execution.

The remote host is running Mac OS X 10.12.6 or Mac OS X 10.13.6 and is missing a security update. It is, therefore, affected by multiple vulnerabilities :

  - An application may be able to read restricted memory     (CVE-2019-8691, CVE-2019-8692, CVE-2019-8693)

  - Extracting a zip file containing a symbolic link to an     endpoint in an NFS mount that is attacker controlled may     bypass Gatekeeper (CVE-2019-8656)

  - A remote attacker may be able to cause arbitrary code     execution (CVE-2019-8648, CVE-2018-19860, CVE-2019-8661)

  - A remote attacker may be able to leak memory     (CVE-2019-8646, CVE-2019-8663)

  - A remote attacker may be able to cause unexpected     application termination or arbitrary code execution     ( CVE-2019-8641, CVE-2019-8660)

  - An application may be able to execute arbitrary code     with system privileges (CVE-2019-8695, CVE-2019-8697)

  - An issue existed in Samba that may allow attackers to     perform unauthorized actions by intercepting     communications between services (CVE-2018-16860)

  - An application may be able to execute arbitrary code     with kernel privileges (CVE-2019-8694)

  - A remote attacker may be able to view sensitive     information (CVE-2019-13118)

  - An attacker may be able to trigger a use-after-free in     an application deserializing an untrusted NSDictionary     (CVE-2019-8662)

  - Visiting a malicious website may lead to address bar     spoofing (CVE-2019-8670)

  - The encryption status of a Time Machine backup may be     incorrect (CVE-2019-8667)

  - Parsing a maliciously crafted office document may lead     to an unexpected application termination or arbitrary     code execution (CVE-2019-8657)

  - Processing maliciously crafted web content may lead to     universal cross site scripting (CVE-2019-8649,     CVE-2019-8658, CVE-2019-8690)

  - Processing maliciously crafted web content may lead to     arbitrary code execution (CVE-2019-8644, CVE-2019-8666,     CVE-2019-8669, CVE-2019-8671, CVE-2019-8672,     CVE-2019-8673, CVE-2019-8676, CVE-2019-8677,     CVE-2019-8678, CVE-2019-8679, CVE-2019-8680,     CVE-2019-8681, CVE-2019-8683, CVE-2019-8684,     CVE-2019-8685, CVE-2019-8686, CVE-2019-8687,     CVE-2019-8688, CVE-2019-8689)

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

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

According to its banner, the version of Apple TV on the remote device is prior to 12.4. It is therefore affected by multiple vulnerabilities as described in HT210351.

The version of Apple iOS running on the mobile device is prior to 12.4. It is, therefore, affected by multiple vulnerabilities.
