Descriptions

In GNOME Epiphany before 41.4 and 42.x before 42.2, an HTML document can trigger a client buffer overflow (in ephy_string_shorten in the UI process) via a long page title. The issue occurs because the number of bytes for a UTF-8 ellipsis character is not properly considered.

En GNOME Epiphany versiones anteriores a 41.4 y versiones 42.x anteriores a 42.2, un documento HTML puede desencadenar un desbordamiento del búfer del cliente (en ephy_string_shorten en el proceso de la interfaz de usuario) por medio de un título de página largo. El problema es producido porque el número de bytes para un carácter de elipsis UTF-8 no es considerado apropiadamente
