Executive Summary

This vulnerability is an Out-of-bounds Read in Substance3D - Modeler versions 1.22.4 and earlier. It allows an attacker to read memory outside the intended boundaries, potentially exposing sensitive information stored in memory. Exploiting this requires a victim to open a malicious file.

Impact Analysis

The vulnerability can lead to disclosure of sensitive information stored in memory, which could compromise confidentiality. Since exploitation requires user interaction (opening a malicious file), it could be used to leak sensitive data if a user is tricked into opening such a file.

Mitigation Strategies

To mitigate this vulnerability, avoid opening files from untrusted or unknown sources in Substance3D - Modeler versions 1.22.4 and earlier. Ensure that users are aware of the risk of opening malicious files. Update Substance3D - Modeler to a version later than 1.22.4 once a patch is available.
