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 •
CVSS: 7.8EPSS: 52%CPEs: 20EXPL: 2CVE-2017-8291 – Artifex Ghostscript Type Confusion Vulnerability
https://notcve.org/view.php?id=CVE-2017-8291
Artifex Ghostscript through 2017-04-26 allows -dSAFER bypass and remote command execution via .rsdparams type confusion with a "/OutputFile (%pipe%" substring in a crafted .eps document that is an input to the gs program, as exploited in the wild in April 2017. Artifex Ghostscript permite sobrepasar -dSAFER y la ejecución de comandos remotos a través de una vulnerabilidad de type confusion en .rsdparams con una subcadena "/ OutputFile (% pipe%" en un documento .eps que se utilice como entrada al gs. It was found that ghostscript did not properly validate the parameters passed to the .rsdparams and .eqproc functions. During its execution, a specially crafted PostScript document could execute code in the context of the ghostscript process, bypassing the -dSAFER protection. Artifex Ghostscript allows -dSAFER bypass and remote command execution via .rsdparams type confusion with a "/OutputFile. • https://www.exploit-db.com/exploits/41955 http://openwall.com/lists/oss-security/2017/04/28/2 http://www.debian.org/security/2017/dsa-3838 http://www.securityfocus.com/bid/98476 https://access.redhat.com/errata/RHSA-2017:1230 https://bugs.ghostscript.com/show_bug.cgi?id=697808 https://bugzilla.redhat.com/show_bug.cgi?id=1446063 https://bugzilla.suse.com/show_bug.cgi?id=1036453 https://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=04b37bbce174eed24edec7ad5b920eb93db4d47d • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
