CVE-2019-10216  (opens in a new tab)
CWE-648  (opens in a new tab)

How to fix?

Upgrade Alpine:3.20 ghostscript to version 9.27-r2 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 Alpine. See How to fix? for Alpine:3.20 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.
