https://notcve.org/view.php?id=CVE-2019-14811
A flaw was found in, ghostscript versions prior to 9.50, in the .pdf_hook_DSC_Creator procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands. Se detecto un defecto en, ghostscript en versiones anteriores a la 9.50, en el procedimiento .pdf_hook_DSC_Creator donde no aseguró adecuadamente sus llamadas privilegiadas, permitiendo que los scripts omitieran las restricciones `-dSAFER`.

https://notcve.org/view.php?id=CVE-2019-10216
In ghostscript before version 9.50, the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges and access files outside of restricted areas. En ghostscript anterior a la versión 9.50, el procedimiento .buildfont1 no aseguraba adecuadamente sus llamadas privilegiadas, permitiendo que los scripts eludieran las restricciones `-dSAFER`. Un atacante podría abusar de esta fallo al crear un archivo PostScript especialmente diseñado que podría escalar privilegios y acceder a archivos fuera de las áreas restringidas. It was found that the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=5b85ddd19 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10216 https://security.gentoo.org/glsa/202004-03 https://access.redhat.com/security/cve/CVE-2019-10216 https://bugzilla.redhat.com/show_bug.cgi?id=1737080 • CWE-648: Incorrect Use of Privileged APIs •
