2. Relevant releases/architectures:
Red Hat CodeReady Linux Builder (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64
Red Hat Enterprise Linux AppStream (v. 8) - aarch64, ppc64le, s390x, x86_64
3. Description:
The Ghostscript suite contains utilities for rendering PostScript and PDF
documents. Ghostscript translates PostScript code to common bitmap formats
so that the code can be displayed or printed.
The following packages have been upgraded to a later upstream version:
ghostscript (9.27). (BZ#1874523)
Security Fix(es):
