A validation issue was addressed with improved logic. This issue is fixed in macOS Big Sur 11.4, Security Update 2021-003 Catalina, Security Update 2021-004 Mojave, iOS 14.6 and iPadOS 14.6. Processing a maliciously crafted image may lead to arbitrary code execution.

The version of Apple iOS running on the mobile device is prior to 14.6. It is, therefore, affected by multiple vulnerabilities.

The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.4 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

 - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30712)

  - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30678)

  - An application may be able to execute arbitrary code with kernel privileges. (CVE-2021-30704)

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

The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Security Update 2021-004 Mojave. It is, therefore, affected by multiple vulnerabilities, including the following:

  - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30712)

  - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30678)

  - An application may be able to execute arbitrary code with kernel privileges. (CVE-2021-30704)

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

The remote host is running a version of macOS / Mac OS X that is 10.15.x prior to 10.15.7 Security Update 2021-003 Catalina. It is, therefore, affected by multiple vulnerabilities, including the following:

  - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30712)

  - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30678)

  - An application may be able to execute arbitrary code with kernel privileges. (CVE-2021-30704)
