Technical details

An out-of-bounds write vulnerability (CWE-787) exists in Adobe Substance 3D Sampler versions 6.0.0 and earlier. The flaw is triggered when the application processes a specially crafted malicious file, leading to memory corruption. An attacker can leverage this to execute arbitrary code in the context of the current user. Exploitation requires local access to deliver the file and relies on user interaction (opening the file). Adobe has addressed this in security bulletin APSB26-60.
