https://notcve.org/view.php?id=CVE-2018-20662
In Poppler 0.72.0, PDFDoc::setup in PDFDoc.cc allows attackers to cause a denial-of-service (application crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF file in which an xref data structure is mishandled during extractPDFSubtype processing. En la versión 0.72.0 de Poppler, PDFDoc::setup en PDFDoc.cc permite a los atacantes remotos provocar una denegación de servicio (cierre inesperado de la aplicación provocado por un SIGABRT en Object.h debido a un valor de retorno incorrecto de PDFDoc::setup) manipulando un archivo PDF en el que la estructura de datos xref se maneja de manera incorrecta durante el procesamiento de extractPDFSubtype. • https://access.redhat.com/errata/RHSA-2019:2022 https://access.redhat.com/errata/RHSA-2019:2713 https://gitlab.freedesktop.org/poppler/poppler/commit/9fd5ec0e6e5f763b190f2a55ceb5427cfe851d5f https://gitlab.freedesktop.org/poppler/poppler/issues/706 https://lists.debian.org/debian-lts-announce/2019/03/msg00008.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6OSCOYM3AMFFBJWSBWY6VJVLNE5JD7YS https://li • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2018-20650
A reachable Object::dictLookup assertion in Poppler 0.72.0 allows attackers to cause a denial of service due to the lack of a check for the dict data type, as demonstrated by use of the FileSpec class (in FileSpec.cc) in pdfdetach. Una aserción alcanzable en Object::dictLookup en Poppler 0.72.0 permite a los atacantes provocar una denegación de servicio (DoS) debido a la falta de comprobación del tipo de datos del directorio, tal y como queda demostrado con el uso de la clase FileSpec (en FileSpec.cc) en pdfdetach. • http://www.securityfocus.com/bid/106459 https://access.redhat.com/errata/RHSA-2019:2022 https://access.redhat.com/errata/RHSA-2019:2713 https://gitlab.freedesktop.org/poppler/poppler/commit/de0c0b8324e776f0b851485e0fc9622fc35695b7 https://gitlab.freedesktop.org/poppler/poppler/issues/704 https://lists.debian.org/debian-lts-announce/2019/09/msg00033.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.debian.org/debian-lts-announce/2022/09/msg00030.html https:/ • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2018-19134
In Artifex Ghostscript through 9.25, the setpattern operator did not properly validate certain types. A specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of failure to check whether the Implementation of a pattern dictionary was a structure type. En Artifex Ghostscript hasta la versión 9.25, el operador setpattern no validaba ciertos tipos correctamente. Un documento PostScript especialmente manipulado podría explotar esto para provocar el cierre inesperado de Ghostscript o ejecutar código arbitrario en el contexto del proceso Ghostscript. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=693baf02152119af6e6afd30bb8ec76d14f84bbf http://www.securityfocus.com/bid/106278 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.ghostscript.com/show_bug.cgi?id=700141 https://lists.debian.org/debian-lts-announce/2018/12/msg00019.html https://semmle.com/news/semmle-discovers-severe-vulnerability-ghostscript-postscript-pdf https://www.ghostscript.com/doc/9.26/News.htm https://access.redhat.com/security/cve/CVE-2018-19134 htt • CWE-704: Incorrect Type Conversion or Cast •
CVSS: 9.8EPSS: 1%CPEs: 18EXPL: 0CVE-2018-18493 – Mozilla: Buffer overflow in accelerated 2D canvas with Skia
https://notcve.org/view.php?id=CVE-2018-18493
A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. Puede ocurrir un desbordamiento de búfer en la librería SKIA durante los cálculos de un desplazamiento de búfer con acciones de hardware aceleradas de CANVAS 2D, debido al uso de cálculos de 32-bit en vez de 64-bit. Esto resulta en un cierre inesperado potencialmente explotable. • http://www.securityfocus.com/bid/106168 https://access.redhat.com/errata/RHSA-2018:3831 https://access.redhat.com/errata/RHSA-2018:3833 https://access.redhat.com/errata/RHSA-2019:0159 https://access.redhat.com/errata/RHSA-2019:0160 https://bugzilla.mozilla.org/show_bug.cgi?id=1504452 https://lists.debian.org/debian-lts-announce/2018/12/msg00002.html https://security.gentoo.org/glsa/201903-04 https://usn.ubuntu.com/3844-1 https://usn.ubuntu.com/3868-1 https:/&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
