Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists in the error function in ssg/ssgParser.cxx due to boundary error. A remote attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system via a specially crafted 3d model file that triggers a long error message, as demonstrated by a .ase file.

Successful exploitation of the vulnerability may result in system compromise.
