Description

An issue was discovered in libgpac.a in GPAC 0.8.0, as demonstrated by MP4Box. audio_sample_entry_Read in isomedia/box_code_base.c does not properly decide when to make gf_isom_box_del calls. This leads to various use-after-free outcomes involving mdia_Read, gf_isom_delete_movie, and gf_isom_parse_movie_boxes.

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
