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 file, leading to memory corruption. An attacker can leverage this to execute arbitrary code in the context of the current user. This is a local attack vector that requires user interaction, specifically the opening of a malicious file. Adobe has addressed this issue in newer versions, and users are encouraged to update to the latest release.
