high Nessus Plugin ID 169889


The Adobe InCopy instance installed on the remote host is affected by multiple vulnerabilities.


The version of Adobe InCopy installed on the remote host is prior to 17.4.1, 18.1. It is, therefore, affected by multiple vulnerabilities as referenced in the APSB23-08 advisory.

- Adobe InCopy versions 17.2 (and earlier) and 16.4.1 (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-2022-34252)

- Heap-based Buffer Overflow (CWE-122) potentially leading to Arbitrary code execution (CVE-2023-21594)

- Out-of-bounds Write (CWE-787) potentially leading to Arbitrary code execution (CVE-2023-21595, CVE-2023-21597)

- Improper Input Validation (CWE-20) potentially leading to Arbitrary code execution (CVE-2023-21596)

- Use After Free (CWE-416) potentially leading to Memory leak (CVE-2023-21598)

- Out-of-bounds Read (CWE-125) potentially leading to Memory Leak (CVE-2023-21599)

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 InCopy version 17.4.1, 18.1.0 or later.
