Technical details

The vulnerability involves multiple out-of-bounds write (CWE-787), out-of-bounds read (CWE-125), use-after-free (CWE-416), stack-based buffer overflow (CWE-121), and NULL pointer dereference (CWE-476) flaws in Substance 3D Stager's file parsing logic. Exploitation requires local file access and user interaction (opening a malicious file); the attacker gains arbitrary code execution in the context of the logged-in user. The vendor has released patched versions addressing all reported issues.
