In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect free logic in pagedevice replacement 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 lógica libre incorrecta en el reemplazo pagedevice para provocar el cierre inesperado del intérprete. It was discovered that the ghostscript device cleanup did not properly handle devices replaced with a null 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=241d91112771a6104de10b3948c3f350d6690c1d https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.ghostscript.com/show_bug.cgi?id=699664 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-416: Use After Free •

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 •

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 •
