Synopsis

The version of Adobe Acrobat installed on the remote macOS host is affected by multiple vulnerabilities.

Description

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.
 (CVE-2020-24435)

 - Adobe Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a local privilege escalation vulnerability that could enable a user without administrator privileges to delete arbitrary files and potentially execute arbitrary code as SYSTEM. Exploitation of this issue requires an attacker to socially engineer a victim, or the attacker must already have some access to the environment. (CVE-2020-24433)

 - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) and Adobe Acrobat Pro DC 2017.011.30175 (and earlier) are affected by an improper input validation vulnerability that could result in arbitrary JavaScript execution in the context of the current user. To exploit this issue, an attacker must acquire and then modify a certified PDF document that is trusted by the victim. The attacker then needs to convince the victim to open the document.
 (CVE-2020-24432)

 - 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. (CVE-2020-24439)

 - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) for macOS are affected by a signature verification bypass that could result in local privilege escalation. Exploitation of this issue requires user interaction in that a victim must open a malicious file. (CVE-2020-24429)

 - Acrobat Reader versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by an input validation vulnerability when decoding a crafted codec that could result in the disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file. (CVE-2020-24427)

 - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) for macOS are affected by a security feature bypass that could result in dynamic library code injection by the Adobe Reader process. Exploitation of this issue requires user interaction in that a victim must open a malicious file. (CVE-2020-24431)

 - Acrobat Pro DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by an out-of-bounds write vulnerability that could result in writing past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. This vulnerability requires user interaction to exploit in that the victim must open a malicious document. (CVE-2020-24436)

 - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR.
 Exploitation of this issue requires user interaction in that a victim must open a malicious file.
 (CVE-2020-24426, CVE-2020-24434)

 - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) for macOS are affected by a time-of-check time-of-use (TOCTOU) race condition vulnerability that could result in local privilege escalation. Exploitation of this issue requires user interaction in that a victim must open a malicious file. (CVE-2020-24428)

 - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a use-after-free vulnerability when handling malicious JavaScript. This vulnerability could result in arbitrary code execution in the context of the current user. Exploitation requires user interaction in that a victim must open a malicious file. (CVE-2020-24430)

 - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a use-after-free vulnerability in the processing of Format event actions 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-2020-24437)

 - Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a use-after-free vulnerability that could result in a memory address leak.
 Exploitation of this issue requires user interaction in that a victim must open a malicious file.
 (CVE-2020-24438)

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

Solution

Upgrade to Adobe Acrobat version 2017.011.30180 / 2020.001.30010 / 2020.013.20064 or later.
