Descriptions
If a URL using the "file:" protocol is dragged and dropped onto an open tab that is running in a different child process the tab will open a local file corresponding to the dropped URL, contrary to policy. One way to make the target tab open more reliably in a separate process is to open it with the "noopener" keyword. This vulnerability affects Firefox < 60.
Si una URL que utiliza el protocolo "file:" es arrastrada y soltada en una pestaña abierta que se está ejecutando en un proceso hijo diferente, la pestaña abrirá un archivo local correspondiente a la URL soltada, algo que va en contra de la política. Una forma de hacer que la pestaña de destino se abra de forma más fiable en un proceso separado es abrirla con la palabra clave "noopener". Esta vulnerabilidad afecta a las versiones anteriores a la 60 de Firefox.
USN-3645-1 fixed vulnerabilities in Firefox. The update caused an issue where users experienced long UI pauses in some circumstances. This update fixes the problem. Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, bypass same-origin restrictions, conduct cross-site scripting attacks, install lightweight themes without user interaction, spoof the filename in the downloads panel, or execute arbitrary code. Various other issues were also addressed.
