Off-by-one error in the Ins_MINDEX function in the TrueType bytecode interpreter in Ghostscript before 8.71 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a malformed TrueType font in a document that trigger an integer overflow and a heap-based buffer overflow.

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.
