Scroller Redhat
Ubuntu rolls out vital ImageMagick security patch for 18.04 and 20.04 tackling serious vulnerabilities. Update your systems immediately!
An update for ghostscript is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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 parameterspassed 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)
