The gf_dump_setup function in GPAC 1.0.1 allows malicoius users to cause a denial of service (Invalid memory address dereference) via a crafted file in the MP4Box command.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
