3. Description:

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(es):

* 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. (CVE-2017-7207)
