GPAC Multimedia Open Source Project GPAC Project/MP4Box 2.5-DEV-rev1593-gfe88c3545-master is affected by: Buffer Overflow. The impact is: cause a denial of service (local). The component is: filter_core/filter_pid.c (L:574-580): function gf_filter_pid_inst_swap_delete_task() improperly accesses freed objects during PID instance swap/delete cleanup, leading to heap use-after-free. The attack vector is: Local (AV:L): a local, authenticated user who processes a specially crafted MPEG-2 TS/MP4 file with MP4Box can trigger the bug during filter teardown (PID instance swap/delete), causing a crash. ¶¶ In GPAC s MP4Box, gf_filter_pid_inst_swap_delete_task() in filter_core/filter_pid.c may dereference objects after they have been freed when cleaning up PID instances after a swap/delete operation. Crafted inputs (e.g., malformed MPEG-2 TS) can trigger a heap use-after-free and crash; exploitation may be possible.
