Acrobat Reader DC for macOS versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a security feature bypass. While the practical security impact is minimal, a defense-in-depth fix has been implemented to further harden the Adobe Reader update process.

The version of Adobe Acrobat installed on the remote macOS host is a version prior to 2017.011.30180, 2020.001.30010, or 2020.013.20064. It is, therefore, affected by multiple vulnerabilities.

  - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175     (and earlier) are affected by a heap-based buffer overflow vulnerability in the submitForm function,     potentially resulting in arbitrary code execution in the context of the current user. Exploitation     requires user interaction in that a victim must open a crafted .pdf file in Acrobat Reader.
