https://notcve.org/view.php?id=CVE-2018-17183
Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code. Artifex Ghostscript en versiones anteriores a la 9.25 permitía una tabla de excepción de error que puede escribir el usuario. Esta tabla podía ser usada por los atacantes remotos capaces de proporcionar PostScript manipulados para poder sobrescribir o reemplazar manipuladores de errores para inyectar código. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=fb713b3818b52d8a6cf62c951eba2e1795ff9624 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.ghostscript.com/show_bug.cgi?id=699708 https://lists.debian.org/debian-lts-announce/2018/09/msg00038.html https://usn.ubuntu.com/3773-1 https://access.redhat.com/security/cve/CVE-2018-17183 https://bugzilla.redhat.com/show_bug.cgi?id=1632471 • CWE-460: Improper Cleanup on Thrown Exception •
