AVC_DuplicateConfig() at isomedia/avc_ext.c in GPAC 0.7.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file. There is cfg_new->AVCLevelIndication = cfg->AVCLevelIndication; but cfg could be NULL.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
