CVE-2018-11645 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 ghostscript to version 9.18dfsg0-0ubuntu2.9 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ghostscript package and not the ghostscript package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
psi/zfile.c in Artifex Ghostscript before 9.21rc1 permits the status command even if -dSAFER is used, which might allow remote attackers to determine the existence and size of arbitrary files, a similar issue to CVE-2016-7977.
