GPAC MP4box 2.1-DEV-rev574-g9d5bb184b is vulnerable to heap use-after-free via filters/dmx_m2ts.c:470 in m2tsdmx_declare_pid

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
