CVE-2020-11558Public exploit

Process crash via premature ESDS box deletion

Published Apr 5, 2020 · Updated Aug 4, 2024

Use-after-free in GPAC 0.8.0 allows context-dependent attackers to crash MP4Box through a crafted ISO media file. During dump-mode parsing, audio_sample_entry_Read deletes ptr->esd through gf_isom_box_del even though later teardown paths still reach the allocation. The crafted file must be processed with MP4Box -info or -diso; the public demonstration establishes an invalid memory read and process termination, not code execution.
