Descriptions

Add-on updates failed to verify that the add-on ID inside the signed package matched the ID of the add-on being updated. An attacker who could perform a man-in-the-middle attack on the user's connection to the update server and defeat the certificate pinning protection could provide a malicious signed add-on instead of a valid update. This vulnerability affects Firefox ESR < 45.5 and Firefox < 50.

Las actualizaciones de add-ons no verifican si el ID de add-on en el paquete firmado coincide con el ID del add-on que se está ejecutando. Un atacante que pueda realizar un ataque Man-in-the-Middle (MitM) en la conexión del usuario al servidor de actualización y superar la protección de asignación de certificados podría proporcionar un add-on maliciosamente firmado en lugar de una actualización válida. La vulnerabilidad afecta a Firefox ESR en versiones anteriores a la 45.5 y Firefox en versiones anteriores a la 50.

A flaw was found in the way Add-on update process was handled by Firefox. A Man-in-the-Middle attacker could use this flaw to install a malicious signed add-on update.
