CVE-2018-1066

Estado: ModificadaMedia (6.5)—

El kernel de Linux, en versiones anteriores a la 4.11, es vulnerable a una desreferencia de puntero NULL en fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() que permite que un atacante que controla un servidor CIFS provoque un pánico en un cliente con el servidor montado, debido a que un campo TargetInfo en una respuesta de negociación de instalación NTLMSSP se gestiona de manera incorrecta durante la recuperación de sesión.
