CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 1CVE-2018-19134 – ghostscript: Type confusion in setpattern (700141)
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 •
