      "value": "A heap out-of-bounds memory write exists in FFMPEG since version 5.1. The size calculation in `build_open_gop_key_points()` goes through all entries in the loop and adds `sc->ctts_data[i].count` to `sc->sample_offsets_count`. This can lead to an integer overflow resulting in a small allocation with `av_calloc()`. An attacker can cause remote code execution via a malicious mp4 file. We recommend upgrading past commit c953baa084607dd1d84c3bfcce3cf6a87c3e6e05"

El c\u00e1lculo del tama\u00f1o en `build_open_gop_key_points()` recorre todas las entradas del bucle y a\u00f1ade `sc->ctts_data[i].count` a `sc->sample_offsets_count`. Esto puede conducir a un desbordamiento de enteros que resulta en una peque\u00f1a asignaci\u00f3n con `av_calloc()`. Un atacante puede provocar la ejecuci\u00f3n remota de c\u00f3digo a trav\u00e9s de un archivo mp4 malicioso. Recomendamos actualizar el commit c953baa084607dd1d84c3bfcce3cf6a87c3e6e05"
