Examining data/r-cran-rsvg-2.1/src/rsvg.c

FINAL RESULTS:

data/r-cran-rsvg-2.1/src/rsvg.c:35:3:  [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(RAW(image), cairo_image_surface_get_data(canvas), size);
data/r-cran-rsvg-2.1/src/rsvg.c:52:3:  [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(&(mem->buf[mem->size]), data, length);
data/r-cran-rsvg-2.1/src/rsvg.c:70:3:  [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(RAW(res), mem.buf, mem.size);
data/r-cran-rsvg-2.1/src/rsvg.c:88:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
