Technical details
A heap-based buffer overflow vulnerability exists in Adobe Substance3D Designer, allowing arbitrary code execution in the context of the current user. The vulnerability is triggered by parsing a malicious file that the user must open—no network access or elevated privileges are required for exploitation. The attacker must craft a specific file format that, when processed by the application, causes a buffer overrun on the heap, enabling arbitrary code execution with user-level privileges. User interaction (opening a file) is required to trigger the vulnerability.
