https://notcve.org/view.php?id=CVE-2018-18073
Artifex Ghostscript allows attackers to bypass a sandbox protection mechanism by leveraging exposure of system operators in the saved execution stack in an error object. Artifex Ghostscript permite que los atacantes omitan un mecanismo de protección de sandbox aprovechando la exposición de los operadores del sistema en la pila de ejecución guardada en un objeto error. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=34cc326eb2c5695833361887fe0b32e8d987741c http://packetstormsecurity.com/files/149758/Ghostscript-Exposed-System-Operators.html http://www.openwall.com/lists/oss-security/2018/10/10/12 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.chromium.org/p/project-zero/issues/detail?id=1690 https://bugs.ghostscript.com/show_bug.cgi?id=699927 https://lists.debian.org/debian-lts-announce/2018/10/msg00013.html https://usn.ubuntu.com/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-460: Improper Cleanup on Thrown Exception •

https://notcve.org/view.php?id=CVE-2018-17183
Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code. Artifex Ghostscript en versiones anteriores a la 9.25 permitía una tabla de excepción de error que puede escribir el usuario. Esta tabla podía ser usada por los atacantes remotos capaces de proporcionar PostScript manipulados para poder sobrescribir o reemplazar manipuladores de errores para inyectar código. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=fb713b3818b52d8a6cf62c951eba2e1795ff9624 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.ghostscript.com/show_bug.cgi?id=699708 https://lists.debian.org/debian-lts-announce/2018/09/msg00038.html https://usn.ubuntu.com/3773-1 https://access.redhat.com/security/cve/CVE-2018-17183 https://bugzilla.redhat.com/show_bug.cgi?id=1632471 • CWE-460: Improper Cleanup on Thrown Exception •
CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2018-16802 – ghostscript: Incorrect "restoration of privilege" checking when running out of stack during exception handling
https://notcve.org/view.php?id=CVE-2018-16802
An issue was discovered in Artifex Ghostscript before 9.25. Incorrect "restoration of privilege" checking when running out of stack during exception handling could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction. This is due to an incomplete fix for CVE-2018-16509. Se ha descubierto un problema en versiones anteriores a la 9.25 de Artifex Ghostscript. La comprobación incorrecta de "restoration of privilege" al quedarse sin pila durante el manejo de excepciones podría ser empleada por atacantes que sean capaces de proporcionar PostScript manipulado para ejecutar código mediante la instrucción "pipe". • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=3e5d316b72e3965b7968bb1d96baa137cd063ac6 http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=643b24dbd002fb9c131313253c307cf3951b3d47 https://access.redhat.com/errata/RHSA-2018:3834 https://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=5812b1b78fc4d36fdc293b7859de69241140d590 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://seclists.org/oss-sec/2018/q3/228 https://seclists.org/oss-sec/2018/q3/229 https://security • CWE-20: Improper Input Validation •
