ghostscript: CVE-2019-14811, CVE-2019-14817
A flaw was found in, ghostscript versions prior to 9.28,
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.
