https://notcve.org/view.php?id=CVE-2016-7978
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 getenv and filenameforall functions in Ghostscript 9.10 ignore the "-dSAFER" argument, which allows remote attackers to read data via a crafted postscript file. Las funciones getenv y filenameforall en Ghostscript 9.10 ignoran el argumento "-dSAFER", lo que permite a atacantes remotos leer datos a través de un archivo postcript manipulado. It was found that the ghostscript functions getenv and filenameforall 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 and list directory respectively, from the target. • http://rhn.redhat.com/errata/RHSA-2017-0013.html http://rhn.redhat.com/errata/RHSA-2017-0014.html http://www.debian.org/security/2016/dsa-3691 http://www.openwall.com/lists/oss-security/2016/09/29/28 http://www.openwall.com/lists/oss-security/2016/09/29/5 http://www.securityfocus.com/bid/96497 https://bugs.ghostscript.com/show_bug.cgi?id=694724 https://bugs.ghostscript.com/show_bug.cgi?id=697169 https://bugzilla.redhat.com/show_bug.cgi?id=1380327 https:& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2016-8602
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. A specially crafted postscript document could cause a crash, or execute arbitrary code in the context of the gs process. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=f5c7555c303 http://rhn.redhat.com/errata/RHSA-2017-0013.html http://rhn.redhat.com/errata/RHSA-2017-0014.html http://www.debian.org/security/2016/dsa-3691 http://www.openwall.com/lists/oss-security/2016/10/11/5 http://www.openwall.com/lists/oss-security/2016/10/11/7 http://www.securityfocus.com/bid/95311 https://bugs.ghostscript.com/show_bug.cgi?id=697203 https://bugzilla.redhat.com/show_bug.cgi&# • CWE-20: Improper Input Validation CWE-704: Incorrect Type Conversion or Cast •
