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)
