CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2019-14812 – ghostscript: Safer mode bypass by .forceput exposure in setuserparams (701444)
https://notcve.org/view.php?id=CVE-2019-14812
A flaw was found in all ghostscript versions 9.x before 9.50, in the .setuserparams2 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 encontró un fallo en todas las versiones de ghostscript 9.x anteriores a la versión 9.50, en el procedimiento .setuserparams2 donde no aseguraba apropiadamente sus llamadas privilegiadas, permitiendo que los scripts omitieran las restricciones "-dSAFER". Un archivo PostScript especialmente diseñado podría deshabilitar la protección de seguridad y luego tener acceso al sistema de archivos o ejecutar comandos arbitrarios.

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.

Artifex Ghostscript 9.22 is affected by: Obtain Information. The impact is: obtain sensitive information. The component is: affected source code file, affected function, affected executable, affected libga (imagemagick used that). The attack vector is: Someone must open a postscript file though ghostscript. Because of imagemagick also use libga, so it was affected as well. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=2fc463d0e http://www.securityfocus.com/bid/108463 https://bugs.ghostscript.com/show_bug.cgi?id=698676 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2019-3839
It was found that in ghostscript some privileged operators remained accessible from various places after the CVE-2019-6116 fix. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Ghostscript versions before 9.27 are vulnerable.
