(CVE-2013-5653, CVE-2016-7977) * It was found that the ghostscript function .setdevice suffered a use- after-free vulnerability due to an incorrect reference count. A specially crafted postscript document could trigger code execution in the context of the gs process. (CVE-2016-7978) * 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.
