| Doc Text: |
A flaw was found in MuPDF. A remote attacker can exploit an uncontrolled recursion vulnerability in the EPUB CSS rendering engine by supplying a maliciously crafted EPUB file. This file, containing deeply nested HTML elements and inline CSS styles, causes the `value_from_inheritable_property()` function to recurse without a depth limit. This ultimately exhausts the process stack, leading to a denial of service (DoS) by crashing any application using MuPDF for EPUB rendering.
