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

Vulnerability from cvelistv5 – Published: 2026-06-23 17:21 – Updated: 2026-06-23 17:36 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.
