A memory initialization issue was addressed with improved memory handling. This issue is fixed in iTunes 12.11.3 for Windows, Security Update 2021-002 Catalina, Security Update 2021-003 Mojave, iCloud for Windows 12.3, macOS Big Sur 11.3, watchOS 7.4, tvOS 14.5, iOS 14.5 and iPadOS 14.5. Processing maliciously crafted web content may disclose sensitive user information.

The version of Apple iOS running on the mobile device is prior to 14.5. It is, therefore, affected by multiple vulnerabilities.

The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Security Update 2021-003 Mojave It is, therefore, affected by multiple vulnerabilities, including the following:

  - An application may be able to execute arbitrary code with system privileges due to insufficient permission     checks (CVE-2020-3838).

  - A memory corruption vulnerability could allow an application read access to restricted memory (CVE-2021-1808).

  - A memory corruption vulnerability could allow an application to cause unexpected system termination or to     write kernel memory (CVE-2021-1828).

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 2021-002 Catalina It is, therefore, affected by multiple vulnerabilities, including the following:

  - An application may be able to execute arbitrary code with system privileges due to insufficient permission     checks (CVE-2020-3838).

  - A memory corruption vulnerability could allow an application read access to restricted memory (CVE-2021-1808).

  - A memory corruption vulnerability could allow an application to cause unexpected system termination or to     write kernel memory (CVE-2021-1828).

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 11.x prior to 11.3 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

  - A memory corruption issue which could allow an application restricted memory read access (CVE-2021-1808).

  - A memory corruption issue which could allow an application to cause unexpected system termination or to     write kernel memory (CVE-2021-1828).

  - An out-of-bounds wirte issue which could allow a malicious application to execute arbitrary code with     kernel privileges (CVE-2021-1834).

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

The version of Apple iTunes installed on the remote Windows host is prior to 12.11.3. It is, therefore, affected by multiple vulnerabilities as referenced in the HT212319 advisory.

  - In FreeBSD 12.1-STABLE before r364644, 11.4-STABLE before r364651, 12.1-RELEASE before p9, 11.4-RELEASE     before p3, and 11.3-RELEASE before p13, improper handling in the kernel causes a use-after-free bug by     sending large user messages from multiple threads on the same SCTP socket. The use-after-free situation     may result in unintended kernel behaviour including a kernel panic. (CVE-2020-7463)

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