Arch Linux Security Advisory ASA-201705-3
=========================================
Severity: High
Date : 2017-05-07
CVE-ID : CVE-2017-8291
Package : ghostscript
Type : arbitrary command execution
Remote : Yes
Link : https://security.archlinux.org/AVG-256
Summary
=======
The package ghostscript before version 9.21-2 is vulnerable to
arbitrary command execution.
Resolution
==========
Upgrade to 9.21-2.
# pacman -Syu "ghostscript>=9.21-2"
The problem has been fixed upstream but no release is available yet.
Workaround
==========
None.
Description
===========
It was found that ghostscript did not properly validate the parameters
passed to the .rsdparams and .eqproc functions. During its execution, a
specially crafted PostScript document could execute code via a
"/OutputFile (%pipe%" substring in the context of the ghostscript
process, bypassing the -dSAFER protection.
Impact
======
A remote attacker is able to execute arbitrary commands via a specially
crafted PostScript document.
