Description
I see extra bytes in what mysql client sends to server when load data local infile .. is called. The extra bytes appears to be an additional packet which I don't recognize to any known packet. It consists of 4 bytes and includes 0x0 0x0 0x0 0x3 .
ngrep dump caught by exexcuting :
sudo ngrep -x -q -d lo '' > outfile.out
