Use-after-free vulnerability in Ghostscript 9.20 might allow remote attackers to execute arbitrary code via vectors related to a reference leak in .setdevice. Vulnerabilidad de uso después de la liberación de Ghostscript 9.20 podría permitir a atacantes remotos ejecutar código arbitrario a través de vectores relacionados con una fuga de referencia en .setdevice. It was found that the ghostscript function .setdevice suffered a use-after-free vulnerability due to an incorrect reference count.

The .sethalftone5 function in psi/zht2.c in Ghostscript before 9.21 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted Postscript document that calls .sethalftone5 with an empty operand stack. La función .sethalftone5 en psi/zht2.c en Ghostscript en versiones anteriores a 9.21 permite a los atacantes remotos provocar una denegación de servicio (caída de la aplicación) o posiblemente ejecutar código arbitrario a través de un documento Postscript que llama a .sethalftone5 con una pila de operandos vacía. It was found that ghostscript did not sufficiently check the validity of parameters given to the .sethalftone5 function.

https://notcve.org/view.php?id=CVE-2016-7979
Ghostscript before 9.21 might allow remote attackers to bypass the SAFER mode protection mechanism and consequently execute arbitrary code by leveraging type confusion in .initialize_dsc_parser. Ghostscript versiones anteriores a 9.21 podría permitir que los atacantes remotos pasaran por alto el mecanismo de protección del modo SAFER y, en consecuencia, ejecutar código arbitrario mediante el aprovechamiento de la confusión de tipos en .initialize_dsc_parser. It was found that the ghostscript function .initialize_dsc_parser did not validate its parameter before using it, allowing a type confusion flaw.
