How to fix?

Upgrade Amazon-Linux:2 ghostscript to version 0:9.06-8.amzn2.0.5 or higher.
This issue was patched in ALAS2-2018-1088.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ghostscript package and not the ghostscript package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

An issue was discovered in Artifex Ghostscript before 9.25. Incorrect "restoration of privilege" checking when running out of stack during exception handling could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction. This is due to an incomplete fix for CVE-2018-16509.
