Show the technical text from the sources
A flaw was found in Ghostscript as shipped with Red Hat Enterprise Linux 8. The correction for CVE-2019-14869 was omitted during the rebase from version 9.25 to 9.27, leaving privileged .forceput operations in the .charkeys procedure insufficiently protected.
