Name of the Vulnerable Software and Affected Versions GPAC version 1.0.1

Description The issue is related to the trak box size function in the MP4Box command, which allows attackers to cause a denial of service due to a NULL pointer dereference. This can be achieved by using a crafted file. The exploitation of this issue enables a remote attacker to disrupt service.
