CVE-2026-112177: Ghostscript: reintroduction of .charkeys -dsafer bypass in rhel 8

HighCVSS 7.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 29/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.36% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: ghostscript (AlmaLinux:8) 9.27-20.el8_10; ghostscript-doc (AlmaLinux:8) 9.27-20.el8_10; ghostscript-tools-dvipdf (AlmaLinux:8) 9.27-20.el8_10.

Low priority for now. Upgrade to ghostscript (AlmaLinux:8) 9.27-20.el8_10; ghostscript-doc (AlmaLinux:8) 9.27-20.el8_10; ghostscript-tools-dvipdf (AlmaLinux:8) 9.27-20.el8_10 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
