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 Use After Free 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 or equal to 2017.011.30194, 2020.001.30020, or 2021.001.20150. It is, therefore, affected by multiple vulnerabilities.

  - Acrobat Reader DC versions versions 2020.013.20074 (and earlier), 2020.001.30018 (and earlier) and     2017.011.30188 (and earlier) are affected by an Out-of-bounds Write vulnerability when parsing a crafted     jpeg 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-2021-21038, CVE-2021-21044)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Adobe Acrobat installed on the remote Windows host is a version prior or equal to 2017.011.30194, 2020.001.30020, or 2021.001.20150. It is, therefore, affected by multiple vulnerabilities.

  - Out-of-bounds write vulnerabilities that can result in arbitrary code execution. (CVE-2021-21044,     CVE-2021-21038, CVE-2021-21086)

  - Use after free vulnerabilities that can result in arbitrary code execution. (CVE-2021-28562,     CVE-2021-28550, CVE-2021-28553)

  - An out-of-bounds read vulnerability that can result in a memory leak. (CVE-2021-28557)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Adobe Reader installed on the remote Windows host is a version prior or equal to 2017.011.30194, 2020.001.30020, or 2021.001.20150. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Out-of-bounds write vulnerabilities that can result in arbitrary code execution. (CVE-2021-21044,     CVE-2021-21038, CVE-2021-21086)
