CVE-2026-112177
Ghostscript: reintroduction of .charkeys -dsafer bypass in rhel 8
Description
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. Processing a specially crafted PostScript file may allow an attacker to bypass -dSAFER restrictions and access files outside the permitted paths or execute commands with the permissions of the Ghostscript process.
