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 improperly handles memory during the parsing of a specially crafted file. An attacker can exploit this by convincing a victim to open a malicious file, leading to memory corruption and potentially arbitrary code execution in the context of the current user. The attack vector is local with a requirement for user interaction (UI:R). Adobe has addressed this in later versions, and users are advised to update to the latest available release.
