CVE-2025-71382

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.

Summary		(es) MuPDF anterior a 1.27.0-rc1 contiene una vulnerabilidad de recursión incontrolada en el motor de renderizado CSS de EPUB que permite a atacantes remotos causar una denegación de servicio al proporcionar un archivo EPUB maliciosamente diseñado con elementos HTML profundamente anidados y estilos CSS en línea. La función value_from_inheritable_property() en css-apply.c recurre a través de la cadena de herencia de propiedades CSS sin un límite de profundidad, agotando la pila del proceso y causando un fallo en cualquier aplicación que utilice MuPDF para la renderización de EPUB.
