Vulnerability Details
CVEID:
CVE-2016-2118
DESCRIPTION:
Samba could allow a remote attacker to gain elevated privileges on the
system, caused by the acceptance of inadequate authentication levels by the
Microsoft Security Account Manager (SAM) and Local Security Authority (Domain
Policy) (LSAD) remote protocols. An attacker could exploit this vulnerability
using man-in-the-middle techniques to impersonate an authenticated user
against the SAMR or LSAD service and gain access to the Security Account
Manager (SAM) database. This vulnerability is also known as the BADLOCK bug.
CVSS Base Score: 8.3

CVEID:
CVE-2015-5370
DESCRIPTION:
Samba is vulnerable to a denial of service, caused by the improper validation
of DCE-RPC packets by the DCE-RPC client and server implementations. An
attacker could exploit this vulnerability using man-in-the-middle techniques
to downgrade a secure connection to an insecure one and consume all available
CPU resources.

CVEID:
CVE-2016-2110
DESCRIPTION:
Samba could allow a remote attacker to bypass security restrictions, caused
by the failure to protect the feature negotiation of NTLMSSP from a
downgrade. A remote attacker could exploit this vulnerability using man-in-
the-middle techniques to clear NTLMSSP_NEGOTIATE_SIGN and
NTLMSSP_NEGOTIATE_SEAL flags and perform downgrade attacks.

CVEID:
CVE-2016-2111
DESCRIPTION:
Samba could allow a remote attacker to bypass security restrictions, caused
by an error in the NETLOGON service when a Domain Controller is configured. A
remote attacker could exploit this vulnerability using man-in-the-middle
techniques to spoof the computer name of a secure channel's endpoints and
access session-related information of the spoofed computer.
