CVE-2018-16585
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. Note: A reputable source believes that the CVE is potentially a duplicate of CVE-2018-15910 as explained in Red Hat bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=1626193) ** EN DISPUTA ** Se ha descubierto un problema en versiones anteriores a la 9.24 de Artifex Ghostscript. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=1497d65039885a52b598b137dd8622bd4672f9be http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=971472c83a345a16dac9f90f91258bb22dd77f22 https://bugzilla.redhat.com/show_bug.cgi?id=1626193 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://seclists.org/oss-sec/2018/q3/182 https://security.gentoo.org/glsa/201811-12 https://usn.ubuntu.com/3768-1 https://www.debian.org/security/2018/dsa-4288 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVE-2018-16542 – ghostscript: .definemodifiedfont memory corruption if /typecheck is handled (699668)
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 •

https://notcve.org/view.php?id=CVE-2018-16541
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.

CVE-2018-16540 – ghostscript: use-after-free in copydevice handling (699661)
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 •
