CVE-2017-12150 |
It was found that samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8 did not enforce "SMB signing" when certain configuration options were enabled. A remote attacker could launch a man-in-the-middle attack and retrieve information in plain-text. Published: July 26, 2018; 2:29:00 PM -0400 |
V3.1: 7.4 HIGH V2.0: 5.8 MEDIUM |
CVE-2017-12163 |
An information leak flaw was found in the way SMB1 protocol was implemented by Samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8. A malicious client could use this flaw to dump server memory contents to a file on the samba share or to a shared printer, though the exact area of server memory cannot be controlled by the attacker.

V3.0: 7.1 HIGH V2.0: 4.8 MEDIUM |
CVE-2018-1057 |
On a Samba 4 AD DC the LDAP server in all versions of Samba from 4.0.0 onwards incorrectly validates permissions to modify passwords over LDAP allowing authenticated users to change any other users' passwords, including administrative users and privileged service accounts (eg Domain Controllers). Published: March 13, 2018; 12:29:00 PM -0400 |
V3.1: 8.8 HIGH V2.0: 6.5 MEDIUM |
CVE-2018-1050 |
All versions of Samba from 4.0.0 onwards are vulnerable to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon. Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash. Published: March 13, 2018; 12:29:00 PM -0400 |
V3.1: 4.3 MEDIUM V2.0: 3.3 LOW |
CVE-2017-2619 |
Samba before versions 4.6.1, 4.5.7 and 4.4.11 are vulnerable to a malicious client using a symlink race to allow access to areas of the server file system not exported under the share definition. Published: March 12, 2018; 11:29:00 AM -0400 |
V3.1: 7.5 HIGH V2.0: 6.0 MEDIUM |
CVE-2017-15275 |
Samba before 4.7.3 might allow remote attackers to obtain sensitive information by leveraging failure of the server to clear allocated heap memory. Published: November 27, 2017; 5:29:00 PM -0500 |
V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2017-14746 |
Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote attackers to execute arbitrary code via a crafted SMB1 request. Published: November 27, 2017; 5:29:00 PM -0500 |
V3.1: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2017-11103 |
Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks. NOTE: this CVE is only for Heimdal and other products that embed Heimdal code; it does not apply to other instances in which this part of the Kerberos 5 protocol specification is violated.

V3.1: 8.1 HIGH V2.0: 6.8 MEDIUM |
CVE-2017-9461 |
smbd in Samba before 4.4.10 and 4.5.x before 4.5.6 has a denial of service vulnerability (fd_open_atomic infinite loop with high CPU usage and memory consumption) due to wrongly handling dangling symlinks. Published: June 06, 2017; 5:29:00 PM -0400 |
V3.0: 6.5 MEDIUM V2.0: 6.8 MEDIUM |
CVE-2017-7494 |
Samba since version 3.5.0 and before 4.6.4, 4.5.10 and 4.4.14 is vulnerable to remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it. Published: May 30, 2017; 2:29:00 PM -0400 |
V3.1: 9.8 CRITICAL V2.0: 10.0 HIGH |
CVE-2016-2126 |
Samba version 4.0.0 up to 4.5.2 is vulnerable to privilege elevation due to incorrect handling of the PAC (Privilege Attribute Certificate) checksum. A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions. Published: May 11, 2017; 10:29:58 AM -0400 |
V3.1: 6.5 MEDIUM V2.0: 4.0 MEDIUM |
CVE-2016-2119 |
libcli/smb/smbXcli_base.c in Samba 4.x before 4.2.14, 4.3.x before 4.3.11, and 4.4.x before 4.4.5 allows man-in-the-middle attackers to bypass a client-signing protection mechanism, and consequently spoof SMB2 and SMB3 servers, via the (1) SMB2_SESSION_FLAG_IS_GUEST or (2) SMB2_SESSION_FLAG_IS_NULL flag. Published: July 07, 2016; 11:59:00 AM -0400 |
V3.1: 7.5 HIGH V2.0: 6.8 MEDIUM |
CVE-2016-2115 |
Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not require SMB signing within a DCERPC session over ncacn_np, which allows man-in-the-middle attackers to spoof SMB clients by modifying the client-server data stream. Published: April 24, 2016; 8:59:06 PM -0400 |
V3.0: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2016-2114 |
The SMB1 protocol implementation in Samba 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not recognize the "server signing = mandatory" setting, which allows man-in-the-middle attackers to spoof SMB servers by modifying the client-server data stream. Published: April 24, 2016; 8:59:05 PM -0400 |
V3.0: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2016-2113 |
Samba 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not verify X.509 certificates from TLS servers, which allows man-in-the-middle attackers to spoof LDAPS and HTTPS servers and obtain sensitive information via a crafted certificate. Published: April 24, 2016; 8:59:03 PM -0400 |
V3.0: 7.4 HIGH V2.0: 5.8 MEDIUM |
CVE-2016-2112 |
The bundled LDAP client library in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not recognize the "client ldap sasl wrapping" setting, which allows man-in-the-middle attackers to perform LDAP protocol-downgrade attacks by modifying the client-server data stream. Published: April 24, 2016; 8:59:03 PM -0400 |
V3.0: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2016-2111 |
The NETLOGON service in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2, when a domain controller is configured, allows remote attackers to spoof the computer name of a secure channel's endpoint, and obtain sensitive session information, by running a crafted application and leveraging the ability to sniff network traffic, a related issue to CVE-2015-0005. Published: April 24, 2016; 8:59:02 PM -0400 |
V3.0: 6.3 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2016-2110 |
The NTLMSSP authentication implementation in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 allows man-in-the-middle attackers to perform protocol-downgrade attacks by modifying the client-server data stream to remove application-layer flags or encryption settings, as demonstrated by clearing the NTLMSSP_NEGOTIATE_SEAL or NTLMSSP_NEGOTIATE_SIGN option to disrupt LDAP security. Published: April 24, 2016; 8:59:01 PM -0400 |
V3.0: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2015-5370 |
Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not properly implement the DCE-RPC layer, which allows remote attackers to perform protocol-downgrade attacks, cause a denial of service (application crash or CPU consumption), or possibly execute arbitrary code on a client system via unspecified vectors. Published: April 24, 2016; 8:59:00 PM -0400 |
V3.0: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2016-2118 |
The MS-SAMR and MS-LSAD protocol implementations in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 mishandle DCERPC connections, which allows man-in-the-middle attackers to perform protocol-downgrade attacks and impersonate users by modifying the client-server data stream, aka "BADLOCK."
