Descriptions
An information leak flaw was found in the way SMB1 protocol was implemented by Samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8. A malicious client could use this flaw to dump server memory contents to a file on the samba share or to a shared printer, though the exact area of server memory cannot be controlled by the attacker.
Se ha descubierto una vulnerabilidad de fuga de información en la manera en la que Samba, en versiones anteriores a la 4.4.16, versiones 4.5.x anteriores a la 4.5.14 y versiones 4.6.x anteriores a la 4.6.8, implementó el protocolo SMB1. Un cliente malicioso podría utilizar esta vulnerabilidad para volcar los contenidos de la memoria del servidor en un archivo en el almacenamiento de samba o en una impresora compartida, aunque el atacante no pueda controlar el área exacta de memoria del servidor.
