The specific version of Samba that the system is running is reportedly affected by the following vulnerabilities:

- Samba contains a flaw in the DCE-RPC client that is triggered during the handling of specially crafted DCE-RPC packets. This may allow a remote attacker to conduct a man-in-the-middle attack, downgrade a secure connection to an insecure one, cause a consumption of CPU resources, or potentially execute arbitrary code. (CVE-2015-5370)

- Samba contains a flaw in its implementation of NTLMSSP authentication that may allow a man-in-the-middle attacker to conduct multiple attacks. This may allow the attacker to  clear NTLMSSP_NEGOTIATE_SIGN and NTLMSSP_NEGOTIATE_SEAL, take over connections, cause traffic to be sent without encryption, or potentially have other impacts. (CVE-2016-2110)

- Samba contains a flaw in NETLOGON that is due to the program failing to properly establish a secure channel connection. This may allow a remote man-in-the-middle attacker to spoof a secure channel's endpoints' computer name and potentially obtain session information. (CVE-2016-2111)

- Samba contains a flaw that is due to a lack of integrity protection mechanisms. This may allow a remote man-in-the-middle attacker to downgrade a secure LDAP connection to an insecure version of the connection. (CVE-2016-2112)

- Samba contains a flaw as TLS certificates are not properly validated for the LDAP and HTTP protocols. By spoofing the server via a certificate that appears valid, an attacker with the ability to intercept network traffic (e.g. MitM, DNS cache poisoning) can disclose and optionally manipulate transmitted data. (CVE-2016-2113)

- Samba contains a flaw that is due to the program failing to enforce the 'server signing = mandatory' option in smb.conf for clients using the SMB1 protocol. This may result in SMB signing not being properly required, potentially allowing a man-in-the-middle attacker to conduct spoofing attacks. (CVE-2016-2114)

- Samba contains a flaw that is due to the program failing to perform integrity checks for SMB client connections. As the protection mechanisms for DCERPC communication sessions are inherited from the underlying SMB connection, this may allow a man-in-the-middle attacker to conduct spoofing attacks. (CVE-2016-2115)

Versions of Samba prior to 4.2.10 / 4.2.11, 4.3.7 / 4.3.8 and 4.4.1 / 4.4.2 are unpatched for the badlock vulnerability.

Based on the system log, this system is running Samba.
