Acrobat Reader DC versions 2021.005.20054 (and earlier), 2020.004.30005 (and earlier) and 2017.011.30197 (and earlier) are affected by a Heap-based Buffer overflow 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.

The version of Adobe Acrobat installed on the remote macOS host is a version prior to 2017.011.30199, 2020.004.30006, or 2021.005.20058. It is, therefore, affected by multiple vulnerabilities.

  - Acrobat Reader DC versions 2021.005.20054 (and earlier), 2020.004.30005 (and earlier) and 2017.011.30197     (and earlier) are affected by an Improper Neutralization of Special Elements used in an OS Command. An     authenticated attacker could leverage this vulnerability to achieve arbitrary code execution on the host     machine in the context of the current user. Exploitation of this issue requires user interaction in that a     victim must open a malicious file. (CVE-2021-28634)
