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

Description The issue is a Heap-based Buffer Overflow that 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 is caused by a buffer overflow in dynamic 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 Heap-based Buffer Overflow issue to prevent arbitrary code execution. As a temporary workaround, consider avoiding the use of SVG file parsing until a patch is available. Restrict access to potentially malicious files to minimize the risk of exploitation.
