ghostscript before version 9.21 is vulnerable to a heap based buffer overflow that was found in the ghostscript jbig2_decode_gray_scale_image function which is used to decode halftone segments in a JBIG2 image. A document (PostScript or PDF) with an embedded, specially crafted, jbig2 image could trigger a segmentation fault in ghostscript.
