CVE-2020-14212  (opens in a new tab)
CWE-787  (opens in a new tab)

How to fix?

Upgrade Alpine:3.12 ffmpeg to version 4.3.1-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ffmpeg package and not the ffmpeg package as distributed by Alpine. See How to fix? for Alpine:3.12 relevant fixed versions and status.

FFmpeg through 4.3 has a heap-based buffer overflow in avio_get_str in libavformat/aviobuf.c because dnn_backend_native.c calls ff_dnn_load_model_native and a certain index check is omitted.
