CVE-2024-47546

Application crash via closed-caption length underflow

Published Dec 11, 2024 · Updated Nov 3, 2025

Integer underflow in GStreamer's MP4/MOV demuxer before 1.24.10 allows local users to crash media applications through crafted files. In extract_cc_from_data in qtdemux.c, a c708 atom shorter than eight bytes wraps atom_length - 8 to a large cclen value passed to g_memdup2 for an out-of-bounds read. The file must reach closed-caption parsing; the read can span process memory or terminate the consuming application.
