  - Acrobat Reader DC versions versions 2021.001.20155 (and earlier), 2020.001.30025 (and earlier) and
    2017.011.30196 (and earlier) are affected by an Out-of-bounds Read 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-2021-28554)
