Technical details
An out-of-bounds write vulnerability exists in Substance3D Stager versions 3.1.7 and earlier. The vulnerability is triggered when processing a malicious file, allowing an attacker to write data outside allocated memory boundaries. This leads to arbitrary code execution with the privileges of the current user. Exploitation requires user interaction—a victim must open a malicious file. The vulnerability affects Windows and/or macOS systems running the affected versions. A patch is expected to be available through Adobe's standard security update channels.
