A null pointer dereference issue was discovered in FFmpeg in decode_main_header() function of libavformat/nutdec.c file. The flaw occurs because the function lacks check of the return value of avformat_new_stream() and triggers the null pointer dereference error, causing an application to crash.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
