Descripción |
|
|
Se ha descubierto una vulnerabilidad en fetchmail en versiones anteriores a la 6.3.6-rc. La vulnerabilidad reside en que fetchmail no impone la conexión TLS y podría transmitir contraseñas sin encriptar a través de links no seguros si se producen ciertas circunstancias no especificadas. Un atacante remoto podría obtener información sensible mediante un ataque de "man in the middle" (MiTM). |
