CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2018-15910 – ghostscript: LockDistillerParams type confusion (699656)
https://notcve.org/view.php?id=CVE-2018-15910
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the LockDistillerParams parameter to crash the interpreter or execute code. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear una confusión de tipos en el parámetro LockDistillerParams para provocar el cierre inesperado del intérprete o ejecutar código. It was discovered that the type of the LockDistillerParams parameter is not properly verified. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=c3476dde7743761a4e1d39a631716199b696b880 http://www.securityfocus.com/bid/105122 https://access.redhat.com/errata/RHSA-2018:2918 https://bugs.ghostscript.com/show_bug.cgi?id=699656 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44101 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://security.gentoo.org/glsa/201811-12 https://support.f5.com/csp/article/K22141757?utm_source=f5support&%3Butm_medium= • CWE-704: Incorrect Type Conversion or Cast •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2018-11645 – ghostscript: status command permitted with -dSAFER in psi/zfile.c allowing attackers to identify the size and existence of files
https://notcve.org/view.php?id=CVE-2018-11645
psi/zfile.c in Artifex Ghostscript before 9.21rc1 permits the status command even if -dSAFER is used, which might allow remote attackers to determine the existence and size of arbitrary files, a similar issue to CVE-2016-7977. psi/zfile.c en Artifex Ghostscript en versiones anteriores a la 9.21rc1 permite el comando status incluso si se emplea -dSAFER, lo que podría permitir que atacantes remotos determinen la existencia y tamaño de archivos arbitrarios. Este problema es similar a CVE-2016-7977. Ghostscript did not honor the -dSAFER option when executing the "status" instruction, which can be used to retrieve information such as a file's existence and size. A specially crafted postscript document could use this flow to gain information on the targeted system's filesystem content. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=b60d50b7567369ad856cebe1efb6cd7dd2284219 https://access.redhat.com/errata/RHSA-2019:2281 https://bugs.ghostscript.com/show_bug.cgi?id=697193 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://usn.ubuntu.com/3768-1 https://www.debian.org/security/2018/dsa-4336 https://access.redhat.com/security/cve/CVE-2018-11645 https://bugzilla.redhat.com/show_bug.cgi?id=1585914 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2018-10194
The set_text_distance function in devices/vector/gdevpdts.c in the pdfwrite component in Artifex Ghostscript through 9.22 does not prevent overflows in text-positioning calculation, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document. La función set_text_distance en devices/vector/gdevpdts.c en el componente pdfwrite en Artifex Ghostscript, hasta la versión 9.22, no evita los desbordamientos en el cálculo de posicionamiento de texto.

CVSS: 7.8EPSS: 52%CPEs: 20EXPL: 2CVE-2017-8291 – Artifex Ghostscript Type Confusion Vulnerability
https://notcve.org/view.php?id=CVE-2017-8291
Artifex Ghostscript through 2017-04-26 allows -dSAFER bypass and remote command execution via .rsdparams type confusion with a "/OutputFile (%pipe%" substring in a crafted .eps document that is an input to the gs program, as exploited in the wild in April 2017. Artifex Ghostscript permite sobrepasar -dSAFER y la ejecución de comandos remotos a través de una vulnerabilidad de type confusion en .rsdparams con una subcadena "/ OutputFile (% pipe%" en un documento .eps que se utilice como entrada al gs. It was found that ghostscript did not properly validate the parameters passed to the .rsdparams and .eqproc functions. During its execution, a specially crafted PostScript document could execute code in the context of the ghostscript process, bypassing the -dSAFER protection. Artifex Ghostscript allows -dSAFER bypass and remote command execution via .rsdparams type confusion with a "/OutputFile. • https://www.exploit-db.com/exploits/41955 http://openwall.com/lists/oss-security/2017/04/28/2 http://www.debian.org/security/2017/dsa-3838 http://www.securityfocus.com/bid/98476 https://access.redhat.com/errata/RHSA-2017:1230 https://bugs.ghostscript.com/show_bug.cgi?id=697808 https://bugzilla.redhat.com/show_bug.cgi?id=1446063 https://bugzilla.suse.com/show_bug.cgi?id=1036453 https://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=04b37bbce174eed24edec7ad5b920eb93db4d47d • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

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.
