FINAL RESULTS:

data/r-cran-av-0.5.1+dfsg/src/video.c:184:3:  [4] (format) snprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
  snprintf(input_args, sizeof(input_args),
data/r-cran-av-0.5.1+dfsg/src/fft.c:283:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
  memcpy(REAL(out), output->dst_dbl, iter * output_range * sizeof(*output->dst_dbl));
data/r-cran-av-0.5.1+dfsg/src/fft.c:333:7:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
      memcpy(output->dst_int + total_samples * channels, output->buf, n_samples * samplesize);
data/r-cran-av-0.5.1+dfsg/src/fft.c:339:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
  memcpy(INTEGER(out), output->dst_int, total_samples * samplesize);
data/r-cran-av-0.5.1+dfsg/src/info.c:76:5:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
    char layout[1024] = "";
