Technical details
The vulnerability is a heap-based buffer overflow in Substance3D Sampler that can be triggered by opening a malicious file. Heap buffer overflows occur when a program writes data beyond the allocated memory boundary on the heap, potentially allowing an attacker to overwrite adjacent memory and control program execution. The attack requires user interaction—specifically, the victim must open a specially crafted malicious file—making this a local attack vector with user interaction required. Successful exploitation results in arbitrary code execution with the privileges of the current user. Patches are expected to be available through Adobe's security advisory.
