The version of Adobe Reader installed on the remote Windows host is a version prior to 2017.011.30196, 2020.001.30025, or 2021.001.20155. It is, therefore, affected by multiple vulnerabilities.

  - Acrobat Reader DC versions versions 2021.001.20150 (and earlier), 2020.001.30020 (and earlier) and     2017.011.30194 (and earlier) are affected by an Out-of-bounds Read vulnerability in the PDFLibTool     component. 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-2021-28565)

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-2021-28561)
