CVSS: 7.8EPSS: 1%CPEs: 11EXPL: 0CVE-2018-17183 – ghostscript: User-writable error exception table
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 •

An issue was discovered in Artifex Ghostscript before 9.24. The .setdistillerkeys PostScript command is accepted even though it is not intended for use during document processing (e.g., after the startup phase). This leads to memory corruption, allowing remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact.

https://notcve.org/view.php?id=CVE-2018-16542
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use insufficient interpreter stack-size checking during error handling to crash the interpreter. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear una comprobación insuficiente del tamaño de la pila del intérprete durante el manejo de errores para provocar el cierre inesperado del intérprete. It was discovered that ghostscript did not properly handle certain stack overflow error conditions. 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=b575e1ec42cc86f6a58c603f2a88fcc2af699cc8 http://seclists.org/oss-sec/2018/q3/182 http://www.securityfocus.com/bid/105337 https://access.redhat.com/errata/RHSA-2018:2918 https://bugs.ghostscript.com/show_bug.cgi?id=699668 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://security.gentoo.org/glsa/201811-12 https://usn.ubuntu.com/3768-1 https://www.debian.org/security/2018/dsa-4288 https://acc • CWE-787: Out-of-bounds Write •
