The version of Adobe Reader installed on the remote Windows host is a version prior to 2017.011.30202, 2020.004.30015, or 2021.007.20091. It is, therefore, affected by multiple vulnerabilities.
Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199 (and earlier) are affected by a Buffer Overflow vulnerability when parsing a specially crafted PDF 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-2021-39863)
Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199 (and earlier) are affected by an Uncontrolled Search Path Element vulnerability. An attacker could leverage this vulnerability to achieve arbitrary code execution in the context of the current user via DLL hijacking. Exploitation of this issue requires user interaction. (CVE-2021-35982)
Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199 (and earlier) are affected by a use-after-free vulnerability in the processing of the AcroForm buttonGetIcon action that could result in 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-2021-39836)
Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199 (and earlier) are affected by a use-after-free vulnerability in the processing of the AcroForm deleteItemAt action that could result in 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-2021-39837)
Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199 (and earlier) are affected by a use-after-free vulnerability in the processing of the AcroForm buttonGetCaption action that could result in 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-2021-39838)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
