3. Description:

The Ghostscript suite contains utilities for rendering PostScript and PDF
documents. Ghostscript translates PostScript code to common bitmap formats
so that the code can be displayed or printed.

Security Fix(es):

* 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 in the context of
the ghostscript process, bypassing the -dSAFER protection. (CVE-2017-8291)

4. Solution:

described in this advisory, refer to:
