Adobe Acrobat Pro DC versions 2020.013.20074 (and earlier), 2020.001.30018 (and earlier) and 2017.011.30188 (and earlier) are affected by an improper input validation vulnerability. An unauthenticated attacker could leverage this vulnerability to disclose sensitive information 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 Reader installed on the remote macOS host is a version prior to 2017.011.30190, 2020.001.30020, or 2021.001.20135. It is, therefore, affected by multiple vulnerabilities.
