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)

  - Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199
    (and earlier) are affected by an Uncontrolled Search Path Element vulnerability. An attacker could
    leverage this vulnerability to achieve arbitrary code execution in the context of the current user via DLL
    hijacking. Exploitation of this issue requires user interaction. (CVE-2021-35982)

  - Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199
    (and earlier) are affected by a use-after-free vulnerability in the processing of the AcroForm
    buttonGetIcon action that could result in 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.
