Technical details
A stack-based buffer overflow vulnerability exists in Adobe Substance3D Sampler due to improper input validation or bounds checking when processing malicious files. The vulnerability can be exploited by crafting a specially formatted file that, when opened by a user, triggers a buffer overflow on the stack. This allows an attacker to overwrite memory and achieve arbitrary code execution in the context of the current user. User interaction is required—the victim must open the malicious file—which limits the attack vector to social engineering. No patch information is readily available from the provided advisory data.
