A flaw was found in, ghostscript versions before 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.

Some exploits to bypass Safer Mode in Ghostscript

GhostRule This is a series of exploits that bypass SAFER mode of Ghostscript Ghostscript <= 92x The PoC codes shown below allow you to get command execution or file I/O at the privilege of the process even if Ghostscript is running on SAFER mode However, all of them bypass the protection by overwriting the security flags in systemdict therefore they have no longer eff
