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 •

https://notcve.org/view.php?id=CVE-2018-16585
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-2018-16539
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect access checking in temp file handling to disclose contents of files on the system otherwise not readable. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear la comprobación de acceso incorrecta en el manejo de archivos temporales para revelar el contenido de los archivos del sistema que, normalmente, no estarían disponibles. It was discovered that the ghostscript did not properly restrict access to files open prior to enabling the -dSAFER mode. An attacker could possibly exploit this to bypass the -dSAFER protection and disclose the content of affected files via a specially crafted PostScript document. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=a054156d425b4dbdaaa9fda4b5f1182b27598c2b https://access.redhat.com/errata/RHSA-2018:3650 https://bugs.ghostscript.com/show_bug.cgi?id=699658 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.artifex.com/news/ghostscript-security-resolved https://www.debian.org/security/2018/dsa-4288 https://access.redhat.com/security/cve/CVE- • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-377: Insecure Temporary File •

https://notcve.org/view.php?id=CVE-2018-16540
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files to the builtin PDF14 converter could use a use-after-free in copydevice handling to crash the interpreter or possibly have unspecified other impact. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados al convertidor PDF14 integrado podrían emplear un uso de memoria previamente liberada en el manejo de copydevice para provocar el cierre inesperado del intérprete u otro tipo de impacto sin especificar. It was discovered that the ghostscript PDF14 compositor did not properly handle the copying of a device. 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=c432131c3fdb2143e148e8ba88555f7f7a63b25e https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:0229 https://bugs.ghostscript.com/show_bug.cgi?id=699661 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.artifex.com/news/ghostscript-security-resolved https://www.debian.org/security/2018/dsa-4 • CWE-416: Use After Free •
