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.

The version of Adobe Acrobat installed on the remote macOS host is a version prior to 2017.011.30196, 2020.001.30025, or 2021.001.20155. It is, therefore, affected by multiple vulnerabilities.
