Compliance Impact

This vulnerability could lead to arbitrary code execution, potentially allowing unauthorized access to sensitive data. This may impact compliance with GDPR (data protection) and HIPAA (health information security) by risking data breaches or unauthorized disclosure.

Mitigation Strategies

Update Adobe Substance3D Painter to the latest version to patch the heap-based buffer overflow vulnerability. Avoid opening untrusted files from unknown sources to prevent exploitation.
