Name of the Vulnerable Software and Affected Versions
MuPDF versions prior to 1.27.0-rc1
Description
The EPUB CSS rendering engine contains an uncontrolled recursion issue. A remote attacker can trigger a denial of service by providing a specially crafted EPUB file featuring inline CSS styles and deeply nested HTML elements. This occurs because the
value from inheritable property() function in css-apply.c processes the CSS property inheritance chain without a depth limit, leading to process stack exhaustion and a subsequent application crash.Recommendations
Update to version 1.27.0-rc1 or later.
