CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2018-15910 – ghostscript: LockDistillerParams type confusion (699656)
https://notcve.org/view.php?id=CVE-2018-15910
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the LockDistillerParams parameter to crash the interpreter or execute code. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear una confusión de tipos en el parámetro LockDistillerParams para provocar el cierre inesperado del intérprete o ejecutar código. It was discovered that the type of the LockDistillerParams parameter is not properly verified. 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=c3476dde7743761a4e1d39a631716199b696b880 http://www.securityfocus.com/bid/105122 https://access.redhat.com/errata/RHSA-2018:2918 https://bugs.ghostscript.com/show_bug.cgi?id=699656 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44101 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://security.gentoo.org/glsa/201811-12 https://support.f5.com/csp/article/K22141757?utm_source=f5support&%3Butm_medium= • CWE-704: Incorrect Type Conversion or Cast •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2018-11645 – ghostscript: status command permitted with -dSAFER in psi/zfile.c allowing attackers to identify the size and existence of files
https://notcve.org/view.php?id=CVE-2018-11645
psi/zfile.c in Artifex Ghostscript before 9.21rc1 permits the status command even if -dSAFER is used, which might allow remote attackers to determine the existence and size of arbitrary files, a similar issue to CVE-2016-7977. psi/zfile.c en Artifex Ghostscript en versiones anteriores a la 9.21rc1 permite el comando status incluso si se emplea -dSAFER, lo que podría permitir que atacantes remotos determinen la existencia y tamaño de archivos arbitrarios. Este problema es similar a CVE-2016-7977. Ghostscript did not honor the -dSAFER option when executing the "status" instruction, which can be used to retrieve information such as a file's existence and size. A specially crafted postscript document could use this flow to gain information on the targeted system's filesystem content. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=b60d50b7567369ad856cebe1efb6cd7dd2284219 https://access.redhat.com/errata/RHSA-2019:2281 https://bugs.ghostscript.com/show_bug.cgi?id=697193 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://usn.ubuntu.com/3768-1 https://www.debian.org/security/2018/dsa-4336 https://access.redhat.com/security/cve/CVE-2018-11645 https://bugzilla.redhat.com/show_bug.cgi?id=1585914 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2018-10194
The set_text_distance function in devices/vector/gdevpdts.c in the pdfwrite component in Artifex Ghostscript through 9.22 does not prevent overflows in text-positioning calculation, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document. La función set_text_distance en devices/vector/gdevpdts.c en el componente pdfwrite en Artifex Ghostscript, hasta la versión 9.22, no evita los desbordamientos en el cálculo de posicionamiento de texto. Esto permite que atacantes remotos provoquen una denegación de servicio (cierre inesperado de la aplicación) u otro tipo de impacto sin especificar mediante un documento PDF manipulado. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=39b1e54b2968620723bf32e96764c88797714879 http://www.securitytracker.com/id/1040729 https://access.redhat.com/errata/RHSA-2018:2918 https://bugs.ghostscript.com/show_bug.cgi?id=699255 https://lists.debian.org/debian-lts-announce/2018/04/msg00028.html https://security.gentoo.org/glsa/201811-12 https://usn.ubuntu.com/3636-1 https://access.redhat.com/security/cve/CVE-2018-10194 https://bugzilla.redhat.com/show_bug.cgi?id=1569108 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

psi/ztoken.c in Artifex Ghostscript 9.21 mishandles references to the scanner state structure, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PostScript document, related to an out-of-bounds read in the igc_reloc_struct_ptr function in psi/igc.c. El archivo psi/ztoken.c en Artifex Ghostscript versión 9.21, maneja inapropiadamente las referencias a la estructura de estado del escáner, que permite a los atacantes remotos generar una denegación de servicio (bloqueo de aplicación) o posiblemente tener otro impacto no especificado por medio de un documento PostScript creado, relacionado con una lectura fuera de limites de la función igc_reloc_struct_ptr en el archivo psi/igc.c. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=671fd59eb657743aa86fbc1895cb15872a317caa http://www.debian.org/security/2017/dsa-3986 http://www.securitytracker.com/id/1039233 https://bugs.ghostscript.com/show_bug.cgi?id=698158 https://security.gentoo.org/glsa/201811-12 • CWE-125: Out-of-bounds Read •

The gs_alloc_ref_array function in psi/ialloc.c in Artifex Ghostscript 9.21 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document. This is related to a lack of an integer overflow check in base/gsalloc.c. La función gs_alloc_ref_array en psi/ialloc.c en Artifex Ghostscript versión 9.21 permite a los atacantes remotos causar una denegación de servicio (DoS) (desbordamiento de búfer en la región heap de la memoria y bloqueo de la aplicación) o posiblemente tener otro impacto no especificado por medio de un documento PostScript creado.
