Patch by David Nowotny In make_matrix (channelmix-ops.c), the matrix-filling loop at the done: label allows the index i (and j in the inner loop) to grow beyond MAX_CHANNELS when dst_paired/src_paired has sparse bits set. In that case the continue fires for most values of i < CHANNEL_BITS, so i advances much faster than ic, and matrix[i][j] reads off the end of the stack-allocated array. Add bounds guards to both loop conditions so i and j cannot exceed MAX_CHANNELS. Fixes #5176 |
