Description |
|
|
Se ha descubierto una vulnerabilidad en el paquete sendmail de Debian cuando "sasl-bin" es instalado para usar sendmail con sasl. El problema reside en que el script de configuración de sendmail utiliza un usuario y contraseña fijados para inicializar la base de datos sasl. La explotación de esta vulnerabilidad podría permitir a un atacante con conocimientos de sistemas Debian utilizar una instalación de sendmail como la descrita para hacer relay. |
