Name of the Vulnerable Software and Affected Versions Adobe Substance 3D Stager versions 2.0.0 and earlier

Description The issue is caused by improper input validation, which could result in arbitrary code execution in the context of the current user. Exploitation requires user interaction, where a victim must open a malicious file. This can also be described as a buffer overflow in memory, allowing an attacker to execute arbitrary code using a specially crafted file.

Recommendations For Adobe Substance 3D Stager versions 2.0.0 and earlier, update to a version that fixes the improper input validation issue to prevent arbitrary code execution. As a temporary workaround, consider avoiding the use of OBJ file parsing until a patch is available. Restrict access to malicious files to minimize the risk of exploitation.
