Summary

Security Advisory ID : BSA-2018-708

Component : Ghostscript

Revision : 1.0: Final

Ghostscript contains an optional -dSAFER option, which is supposed to prevent unsafe PostScript operations. Multiple PostScript operations bypass the protections provided by -dSAFER, which can allow an attacker to execute arbitrary commands with arbitrary arguments. This vulnerability can also be exploited in applications that leverage Ghostscript, such as ImageMagick, GraphicsMagick, evince, Okular, Nautilus, and others. 
Exploit code for this vulnerability is publicly available.

Impact
By causing Ghostscript or a program that leverages Ghostscript to parse a specially-crafted file, a remote, unauthenticated attacker may be able to execute arbitrary commands with the privileges of the Ghostscript code. This action may be triggered with actions as simple as downloading a file from a website. More information at: https://www.kb.cert.org/vuls/id/332928
