ID de Prueba:1.3.6.1.4.1.25623.1.0.844593
Categoría:Ubuntu Local Security Checks
Título:Ubuntu: Security Advisory for samba (USN-4510-1)
Resumen:The remote host is missing an update for the 'samba'; package(s) announced via the USN-4510-1 advisory.
Descripción:Summary:
The remote host is missing an update for the 'samba'
package(s) announced via the USN-4510-1 advisory.

Vulnerability Insight:
Tom Tervoort discovered that the Netlogon protocol implemented by Samba
incorrectly handled the authentication scheme. A remote attacker could use
this issue to forge an authentication token and steal the credentials of
the domain admin.

This update fixes the issue by changing the 'server schannel' setting to
default to 'yes', instead of 'auto', which will force a secure netlogon
channel. This may result in compatibility issues with older devices. A
future update may allow a finer-grained control over this setting.

Affected Software/OS:
'samba' package(s) on Ubuntu 18.04 LTS, Ubuntu 16.04 LTS.

Solution:
Please install the updated package(s).

CVSS Score:
9.3

CVSS Vector:
