CVE-2020-16297 Ghostscript vulnerabilities
Title: Ghostscript vulnerabilities
Summary: Several security issues were fixed in Ghostscript.
It was discovered that Ghostscript incorrectly handled certain document
files. If a user or automated system were tricked into processing a
specially crafted file, a remote attacker could use this issue to cause
Ghostscript to crash, resulting in a denial of service, or possibly
execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.
