Descriptions

In qutebrowser versions less than 1.11.1, reloading a page with certificate errors shows a green URL. After a certificate error was overridden by the user, qutebrowser displays the URL as yellow (colors.statusbar.url.warn.fg). However, when the affected website was subsequently loaded again, the URL was mistakenly displayed as green (colors.statusbar.url.success_https). While the user already has seen a certificate error prompt at this point (or set content.ssl_strict to false, which is not recommended), this could still provide a false sense of security. This has been fixed in 1.11.1 and 1.12.0. All versions of qutebrowser are believed to be affected, though versions before v0.11.x couldn't be tested. Backported patches for older versions (greater than or equal to 1.4.0 and less than or equal to 1.10.2) are available, but no further releases are planned.

En qutebrowser versiones anteriores a 1.11.1, el reinicio de una página con errores de certificado muestra una URL verde. Luego que el usuario haya anulado un error de certificado, qutebrowser muestra la URL en amarillo (colors.statusbar.url.warn.fg). Sin embargo, cuando el sitio web afectado fue cargado posteriormente de nuevo, la URL se mostró erróneamente como verde (colors.statusbar.url.success_https). Aunque el usuario ya ha visto un mensaje de error de certificado en este momento (o establece content.ssl_strict en falso, lo cual no se recomienda), esto aún podría proporcionar una falsa sensación de seguridad. Esto se ha corregido en las versiones 1.11.1 y 1.12.0. Se cree que todas las versiones de qutebrowser están afectadas, aunque las versiones anteriores a v0.11.x no pudieron ser probadas. Los parches con backporting para versiones antiguas (posteriores o iguales a la versión 1.4.0 y versiones anteriores o iguales a 1.10.2) están disponibles, pero no se planean nuevas versiones.
