Summary
flac_enc_fuzzer: Heap-buffer-overflow in append_to_verify_fifo_interleaved_
Details

In appendtoverifyfifointerleaved_ of stream_encoder.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
