CVE-2026-125396 (GCVE-0-2026-125396)

Vulnerability from cvelistv5 – Published: 2026-11-09 23:28 – Updated: 2026-11-09 23:28

Title

Ghostscript before 10.08.0 -dSAFER Bypass via .putgstringcopy .forceput Recovery

Summary

Ghostscript before 10.08.0 contains a -dSAFER bypass vulnerability in the .putgstringcopy procedure in gs_fonts.ps, which calls the privileged .forceput operator without checking operand types. Attackers can supply crafted PostScript or PDF documents that trigger a type error, recover .forceput via a custom error handler, and cause a use-after-free across save/restore to execute arbitrary code.

Severity

8.5 (High)

CVE-2025-71382 (GCVE-0-2025-71382)

Vulnerability from cvelistv5 – Published: 2026-06-23 17:21 – Updated: 2026-11-08 14:00 X_Open Source

Title

MuPDF < 1.27.0-rc1 Stack Exhaustion DoS via EPUB CSS Rendering

Summary

MuPDF before 1.27.0-rc1 contains an uncontrolled recursion vulnerability in the EPUB CSS rendering engine that allows remote attackers to cause a denial of service by supplying a maliciously crafted EPUB file with deeply nested HTML elements and inline CSS styles. The function value_from_inheritable_property() in css-apply.c recurses through the CSS property inheritance chain without a depth limit, exhausting the process stack and causing a crash in any application using MuPDF for EPUB rendering.
