Descriptions

When a master password is set, it is required to be entered again before stored passwords can be accessed in the 'Saved Logins' dialog. It was found that locally stored passwords can be copied to the clipboard thorough the 'copy password' context menu item without re-entering the master password if the master password had been previously entered in the same session, allowing for potential theft of stored passwords. This vulnerability affects Firefox < 68.0.2 and Firefox ESR < 68.0.2.

Cuando se establece una contraseña maestra, es necesario ingresarla nuevamente antes de que pueda ser accedida a las contraseñas almacenadas en el cuadro de diálogo "Saved Logins". Se detectó que las contraseñas almacenadas localmente pueden ser copiadas en el portapapeles por medio del elemento del menú contextual "copy password" sin reingresar la contraseña maestra, si la contraseña maestra ha sido ingresada previamente en la misma sesión, permitiendo el robo potencial de contraseñas almacenadas. Esta vulnerabilidad afecta a Firefox versiones anteriores a 68.0.2 y Firefox ESR versiones anteriores a 68.0.2.
