CVE-2019-10216 Open this link in a new tabHow to fix?
Upgrade RHEL:8 libgs to version 0:9.25-2.el8_0.2 or higher.
This issue was patched in RHSA-2019:2465.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libgs package and not the libgs package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In ghostscript before version 9.50, the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass -dSAFER restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges and access files outside of restricted areas.
