FFmpeg Denial of Service Vulnerability (CNVD-2023-64453)

FFmpeg is a complete solution for recording, converting and streaming audio and video from the FFmpeg team. A denial of service vulnerability exists in FFmpeg, which stems from a lack of return value checking in the decode_main_header() function in the libavformat/nutdec.c file and triggers a null pointer dereference error, which can be exploited by an attacker to cause the application to crash.
