Descriptions

The Cascading Style Sheets (CSS) implementation in Opera before 11.11 does not properly handle the column-count property, which allows remote attackers to cause a denial of service (infinite repaint loop and application hang) via a web page, as demonstrated by an unspecified Wikipedia page.

Las Hojas de Estilo en Cascada (CSS) en la aplicación Opera anterior a v11.11 no controlan correctamente la propiedad column-count lo que permite a atacantes remotos provocar una denegación de servicio (bucle infinito que acaba bloqueando la aplicación) a través de una página web, como lo demuestra una página no especificada de la Wikipedia.
