CWE-648  (opens in a new tab)

How to fix?

Upgrade RHEL:7 libgs to version 0:9.25-2.el7_7.1 or higher.
This issue was patched in RHSA-2019:2462.

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:7 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.
