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 •

GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time.
