CVE-2020-15654 – Mozilla: Custom cursor can overlay user interface
https://notcve.org/view.php?id=CVE-2020-15654
When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user is interacting with the user interface, when they are not. This could lead to a perceived broken state, especially when interactions with existing browser dialogs and warnings do not work. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. Cuando en un bucle infinito, un sitio web que especifica un cursor personalizado usando CSS podría hacer que parezca que el usuario está interactuando con la interfaz de usuario, cuando no es así. Esto podría conllevar a un estado roto percibido, especialmente cuando las interacciones con los diálogos y advertencias del navegador existentes no funcionan. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html https://bugzilla.mozilla.org/show_bug.cgi?id=1648333 https://usn.ubuntu.com/4443-1 https://www.mozilla.org/security/advisories/mfsa2020-30 https://www.mozilla.org/security/advisories/mfsa2020-32 https://www.mozilla.org/security/advisories/mfsa2020-33 https://access.redhat.com/security/cve/CVE-2020-15654 https://bugzilla.redhat.com/show_bug.cgi?id=1861649 • CWE-451: User Interface (UI) Misrepresentation of Critical Information CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
