CVE-2018-11645 (opens in a new tab)How to fix?
Upgrade RHEL:7 ghostscript to version 0:9.25-2.el7 or higher.
This issue was patched in RHSA-2019:2281.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ghostscript package and not the ghostscript package as distributed by RHEL.
See How to fix? for RHEL:7 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.
