Heap-Based Buffer Overflow in Adobe InDesign Enables Code Execution

Executive Summary

This vulnerability is a Heap-based Buffer Overflow found in Adobe InDesign Desktop versions 20.5.2, 21.2, and earlier. It occurs when a user opens a specially crafted malicious file, which can cause the program to overwrite memory in an unintended way.

This overflow can lead to arbitrary code execution, meaning an attacker could run malicious code on the affected system with the privileges of the current user.

Impact Analysis

If exploited, this vulnerability can allow an attacker to execute arbitrary code on your system with the same permissions as the current user.

This could lead to unauthorized actions such as installing malware, stealing data, or taking control of the affected system.

Since exploitation requires opening a malicious file, users must be cautious about files received from untrusted sources.
