Red Hat Security Advisory 2017-0014-01 – 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: It was found that the ghostscript functions getenv, filenameforall and .libfile did not honor the -dSAFER option, usually used when processing untrusted documents, leading to information disclosure. A specially crafted postscript document could read environment variable, list directory and retrieve file content respectively, from the target.
