Out-of-Bounds Read Vulnerability in Adobe InDesign

Impact Analysis

The primary impact of this vulnerability is the potential disclosure of sensitive information from the affected system's memory. An attacker who successfully exploits this issue could gain access to confidential data that should otherwise be protected.

Since exploitation requires user interaction (opening a malicious file), the risk depends on the likelihood of a user being tricked into opening such a file.

Executive Summary

This vulnerability is an out-of-bounds read issue in Adobe InDesign Desktop versions 21.3, 20.5.3, and earlier. It occurs when the software reads memory outside the intended boundaries, which can lead to the disclosure of sensitive information stored in memory.

To exploit this vulnerability, an attacker needs the victim to open a specially crafted malicious file, which triggers the out-of-bounds read and potentially exposes sensitive data.

Compliance Impact

This vulnerability could lead to the disclosure of sensitive information due to an out-of-bounds read in affected versions of Adobe InDesign Desktop. Such unauthorized disclosure of sensitive data may impact compliance with data protection standards and regulations like GDPR and HIPAA, which require safeguarding sensitive information against unauthorized access.

However, exploitation requires user interaction, specifically opening a malicious file, which may reduce the likelihood of automatic or widespread data breaches.

Mitigation Strategies

To mitigate this vulnerability, avoid opening malicious files in affected versions of Adobe InDesign Desktop (versions 21.3, 20.5.3 and earlier). Since exploitation requires user interaction, do not open files from untrusted or unknown sources.

Additionally, update Adobe InDesign Desktop to a version later than 21.3 or 20.5.3 once a patch is available to address this out-of-bounds read vulnerability.
