The version of Adobe Reader installed on the remote macOS host is a version prior to 2017.011.30202, 2020.004.30015, or 2021.007.20091. It is, therefore, affected by multiple vulnerabilities.

  - Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199     (and earlier) are affected by a Buffer Overflow vulnerability when parsing a specially crafted PDF file.
    An unauthenticated attacker could leverage this vulnerability to achieve arbitrary code execution in the     context of the current user. Exploitation of this issue requires user interaction in that a victim must     open a malicious file. (CVE-2021-39863)
