Technical details

A NULL pointer dereference (CWE-476) exists in gf_sg_vrml_field_clone() when cloning a PROTO default SFImage field with a NULL source pointer. The vulnerability occurs during VRML scene graph field duplication when processing malformed input. An attacker can craft an input file to trigger the crash via the affected cloning function, causing denial of service with no authentication or user interaction required beyond file processing.
