Insight
Insight
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): * 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. (CVE-2013-5653, CVE-2016-7977) * It was found that the ghostscript function .initialize_dsc_parser did not validate its parameter before using it, allowing a type confusion flaw. A specially crafted postscript document could cause a crash code execution in the context of the gs process. (CVE-2016-7979) * It was found that ghostscript did not sufficiently check the validity of parameters given to the .sethalftone5 function. A specially crafted postscript document could cause a crash, or execute arbitrary code in the context of the gs process. (CVE-2016-8602)
