Description
Several flaws were found in Samba's implementation of NTLMSSP authentication.
An unauthenticated, man-in-the-middle attacker could use this flaw to clear the
encryption and integrity flags of a connection, causing data to be transmitted
in plain text. The attacker could also force the client or server into sending
data in plain text even if encryption was explicitly requested for that
connection. (CVE-2016-2110)
* It was discovered that Samba configured as a Domain Controller would establish
a secure communication channel with a machine using a spoofed computer name. A
remote attacker able to observe network traffic could use this flaw to obtain
session-related information about the spoofed machine. (CVE-2016-2111)
* It was found that Samba's LDAP implementation did not enforce integrity
protection for LDAP connections. A man-in-the-middle attacker could use this
flaw to downgrade LDAP connections to use no integrity protection, allowing them
to hijack such connections. (CVE-2016-2112)
* It was found that Samba did not enable integrity protection for IPC traffic by
default. A man-in-the-middle attacker could use this flaw to view and modify the
data sent between a Samba server and a client. (CVE-2016-2115)
