The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed. Security Fix: * A NULL pointer dereference flaw was found in ghostscript"s mem_get_bits_rectangle function. A specially crafted postscript document could cause a crash in the context of the gs process.
