Adobe InDesign <= 16.3 Multiple Arbitrary Code Execution Vulnerabilities (APSB21-73)

high Nessus Plugin ID 153437
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host has an application installed that is affected by multiple arbitrary code execution vulnerabilities.


The version of Adobe InDesign installed on the remote Windows host is prior or equal to 16.3. It is, therefore, affected by multiple arbitrary code execution vulnerabilities, as follows:

- Accessing a memory location after the end of the buffer allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2021-39820)

- Out-of-bounds-reads allows a local attacker to execute arbitrary code. (CVE-2021-39821, CVE-2021-39822)

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


Upgrade to Adobe InDesign version 16.4 or later.
