"The version of Adobe Acrobat 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 a memory corruption vulnerability. 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)

  - Acrobat Reader DC versions versions 2021.001.20150 (and earlier), 2020.001.30020 (and earlier) and

    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-2021-28558)

  - 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. An unauthenticated
    attacker could leverage this vulnerability to leak sensitive system information in the context of the
    current user. Exploitation of this issue requires user interaction in that a victim must open a malicious
    file. (CVE-2021-28557)

    2017.011.30194 (and earlier) are affected by an Out-of-bounds Write vulnerability within the ImageTool
    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-2021-28564)

  - Acrobat Reader DC versions versions 2020.013.20074 (and earlier), 2020.001.30018 (and earlier) and
