CVE-2015-3223 1 Samba 1 Samba 2025-04-12 5.0 MEDIUM 5.3 MEDIUM
The ldb_wildcard_compare function in ldb_match.c in ldb before 1.1.24, as used in the AD LDAP server in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, mishandles certain zero values, which allows remote attackers to cause a denial of service (infinite loop) via crafted packets.
CVE-2015-5296 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2025-04-12 4.3 MEDIUM 5.4 MEDIUM
Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 supports connections that are encrypted but unsigned, which allows man-in-the-middle attackers to conduct encrypted-to-unencrypted downgrade attacks by modifying the client-server data stream, related to clidfs.c, libsmb_server.c, and smbXcli_base.c.
CVE-2014-8143 1 Samba 1 Samba 2025-04-12 8.5 HIGH N/A
Samba 4.0.x before 4.0.24, 4.1.x before 4.1.16, and 4.2.x before 4.2rc4, when an Active Directory Domain Controller (AD DC) is configured, allows remote authenticated users to set the LDB userAccountControl UF_SERVER_TRUST_ACCOUNT bit, and consequently gain privileges, by leveraging delegation of authority for user-account or computer-account creation.
CVE-2014-3560 3 Canonical, Redhat, Samba 3 Ubuntu Linux, Enterprise Linux, Samba 2025-04-12 7.9 HIGH N/A
NetBIOS name services daemon (nmbd) in Samba 4.0.x before 4.0.21 and 4.1.x before 4.1.11 allows remote attackers to execute arbitrary code via unspecified vectors that modify heap memory, involving a sizeof operation on an incorrect variable in the unstrcpy macro in string_wrappers.h.
CVE-2016-2114 2 Canonical, Samba 2 Ubuntu Linux, Samba 2025-04-12 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2015-5370 2 Canonical, Samba 2 Ubuntu Linux, Samba 2025-04-12 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2015-8467 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2025-04-12 6.0 MEDIUM 7.5 HIGH
The samldb_check_user_account_control_acl function in dsdb/samdb/ldb_modules/samldb.c in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 does not properly check for administrative privileges during creation of machine accounts, which allows remote authenticated users to bypass intended access restrictions by leveraging the existence of a domain with both a Samba DC and a Windows DC, a similar issue to CVE-2015-2535.
CVE-2014-2855 1 Samba 1 Rsync 2025-04-12 7.8 HIGH N/A
The check_secret function in authenticate.c in rsync 3.1.0 and earlier allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a user name which does not exist in the secrets file.
CVE-2015-5330 1 Samba 1 Samba 2025-04-12 5.0 MEDIUM 7.5 HIGH
ldb before 1.1.24, as used in the AD LDAP server in Samba 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, mishandles string lengths, which allows remote attackers to obtain sensitive information from daemon heap memory by sending crafted packets and then reading (1) an error message or (2) a database value.
CVE-2013-4496 2 Canonical, Samba 2 Ubuntu Linux, Samba 2025-04-12 5.0 MEDIUM N/A
Samba 3.x before 3.6.23, 4.0.x before 4.0.16, and 4.1.x before 4.1.6 does not enforce the password-guessing protection mechanism for all interfaces, which makes it easier for remote attackers to obtain access via brute-force ChangePasswordUser2 (1) SAMR or (2) RAP attempts.
CVE-2015-7560 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2025-04-12 4.0 MEDIUM 6.5 MEDIUM
The SMB1 implementation in smbd in Samba 3.x and 4.x before 4.1.23, 4.2.x before 4.2.9, 4.3.x before 4.3.6, and 4.4.x before 4.4.0rc4 allows remote authenticated users to modify arbitrary ACLs by using a UNIX SMB1 call to create a symlink, and then using a non-UNIX SMB1 call to write to the ACL content.
CVE-2014-0244 1 Samba 1 Samba 2025-04-12 3.3 LOW N/A
The sys_recvfrom function in nmbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a malformed UDP packet.
CVE-2016-2110 2 Canonical, Samba 2 Ubuntu Linux, Samba 2025-04-12 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2015-7540 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2025-04-12 5.0 MEDIUM 7.5 HIGH
The LDAP server in the AD domain controller in Samba 4.x before 4.1.22 does not check return values to ensure successful ASN.1 memory allocation, which allows remote attackers to cause a denial of service (memory consumption and daemon crash) via crafted packets.
CVE-2016-2115 2 Canonical, Samba 2 Ubuntu Linux, Samba 2025-04-12 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2016-2119 1 Samba 1 Samba 2025-04-12 6.8 MEDIUM 7.5 HIGH
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.
CVE-2015-5252 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2025-04-12 5.0 MEDIUM 7.2 HIGH
vfs.c in smbd in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, when share names with certain substring relationships exist, allows remote attackers to bypass intended file-access restrictions via a symlink that points outside of a share.
CVE-2014-0239 1 Samba 1 Samba 2025-04-12 5.0 MEDIUM N/A
The internal DNS server in Samba 4.x before 4.0.18 does not check the QR field in the header section of an incoming DNS message before sending a response, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged response packet that triggers a communication loop, a related issue to CVE-1999-0103.
CVE-2016-0771 1 Samba 1 Samba 2025-04-12 4.9 MEDIUM 5.9 MEDIUM
The internal DNS server in Samba 4.x before 4.1.23, 4.2.x before 4.2.9, 4.3.x before 4.3.6, and 4.4.x before 4.4.0rc4, when an AD DC is configured, allows remote authenticated users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from process memory by uploading a crafted DNS TXT record.
CVE-2016-2113 2 Canonical, Samba 2 Ubuntu Linux, Samba 2025-04-12 5.8 MEDIUM 7.4 HIGH
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.
