  "title": "ffmpeg: A heap out-of-bounds memory write exists in FFMPEG since version 5.1",
  "description": "A heap out-of-bounds memory write exists in FFMPEG since version 5.1. The size calculation in \u0060build_open_gop_key_points()\u0060 goes through all entries in the loop and adds \u0060sc-\u003Ectts_data[i].count\u0060 to \u0060sc-\u003Esample_offsets_count\u0060. This can lead to an integer overflow resulting in a small allocation with \u0060av_calloc()\u0060. An attacker can cause remote code execution via a malicious mp4 file. We recommend upgrading past commit c953baa084607dd1d84c3bfcce3cf6a87c3e6e05",
