Description 

../../../../modules/mux/mpeg/csa.c: In function ‘csa_ComputeKey’:
../../../../modules/mux/mpeg/csa.c:291: attention : array subscript is above array bounds

Indeed, this will overflow during the last iteration (kb[7][9] is out of bounds): 

    for( i = 0; i < 8; i++ )
    {
        kb[7][i+1] = ck[i];
    }
