A validation issue existed in the entitlement verification. This issue was addressed with improved validation of the process entitlement. This issue is fixed in macOS Big Sur 11.0.1, iOS 14.0 and iPadOS 14.0. A malicious application may be able to determine a user's open tabs in Safari.

The remote host is running a version of macOS / Mac OS X that is 11.0.x prior to 11.0.1. It is, therefore, affected by multiple vulnerabilities, including the following:

  - An out-of-bounds write issue that can lead to unexpected application termination or arbitrary code     execution when opening a maliciously crafted PDF file. (CVE-2020-9876)

  - An out-of-bounds write caused by insufficient input validation that can lead to arbitrary code execution     when processing a maliciously crafted image. (CVE-2020-9883)

  - A remote attacker may be able to unexpectedly alter the Mail application date due to insufficient checks.
    (CVE-2020-9941)

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