## Technical details

An out-of-bounds read vulnerability (CWE-125) in Substance 3D Painter's file parsing allows disclosure of adjacent memory contents. The flaw requires local access and user interaction: a victim must open a crafted malicious file. An attacker gains read access to sensitive memory regions; no memory corruption or code execution results from this specific vulnerability, though a related stack-based buffer overflow also exists in the same update.
