CVE-2017-12935

The ReadMNGImage function in coders/png.c in GraphicsMagick 1.3.26 mishandles large MNG images, leading to an invalid memory read in the SetImageColorCallBack function in magick/image.c.

Invalid memory read in SetImageColorCallBack() in image.c (CVE-2017-12935).

Use-after-free in ReadWMFImage() in wmf.c (CVE-2017-12936).

Heap-based buffer overflow in ReadSUNImage() in sun.c (CVE-2017-12937).
