CVE-2017-17433 2 Debian, Samba 2 Debian Linux, Rsync 2024-11-21 4.3 MEDIUM 3.7 LOW
The recv_files function in receiver.c in the daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, proceeds with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allows remote attackers to bypass intended access restrictions.
CVE-2017-16548 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Rsync 2024-11-21 7.5 HIGH 9.8 CRITICAL
The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact by sending crafted data to the daemon.
CVE-2017-15994 1 Samba 1 Rsync 2024-11-21 7.5 HIGH 9.8 CRITICAL
rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for remote attackers to bypass intended access restrictions. NOTE: the rsync development branch has significant use beyond the rsync developers, e.g., the code has been copied for use in various GitHub projects.
CVE-2017-15275 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Samba before 4.7.3 might allow remote attackers to obtain sensitive information by leveraging failure of the server to clear allocated heap memory.
CVE-2017-14746 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote attackers to execute arbitrary code via a crafted SMB1 request.
CVE-2017-12163 3 Debian, Redhat, Samba 7 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 4 more 2024-11-21 4.8 MEDIUM 4.1 MEDIUM
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.
CVE-2017-12151 4 Debian, Hp, Redhat and 1 more 8 Debian Linux, Cifs Server, Enterprise Linux and 5 more 2024-11-21 5.8 MEDIUM 7.4 HIGH
A flaw was found in the way samba client before samba 4.4.16, samba 4.5.14 and samba 4.6.8 used encryption with the max protocol set as SMB3. The connection could lose the requirement for signing and encrypting to any DFS redirects, allowing an attacker to read or alter the contents of the connection via a man-in-the-middle attack.
CVE-2017-12150 3 Debian, Redhat, Samba 7 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 4 more 2024-11-21 5.8 MEDIUM 7.4 HIGH
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.
CVE-2017-11103 5 Apple, Debian, Freebsd and 2 more 6 Iphone Os, Mac Os X, Debian Linux and 3 more 2024-11-21 6.8 MEDIUM 8.1 HIGH
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.
CVE-2016-2126 1 Samba 1 Samba 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
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.
CVE-2016-2125 2 Redhat, Samba 8 Enterprise Linux Desktop, Enterprise Linux Server, Enterprise Linux Server Aus and 5 more 2024-11-21 3.3 LOW 6.5 MEDIUM
It was found that Samba before versions 4.5.3, 4.4.8, 4.3.13 always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users.
CVE-2016-2124 5 Canonical, Debian, Fedoraproject and 2 more 24 Ubuntu Linux, Debian Linux, Fedora and 21 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
CVE-2016-2123 1 Samba 1 Samba 2024-11-21 6.5 MEDIUM 8.8 HIGH
A flaw was found in samba versions 4.0.0 to 4.5.2. The Samba routine ndr_pull_dnsp_name contains an integer wrap problem, leading to an attacker-controlled memory overwrite. ndr_pull_dnsp_name parses data from the Samba Active Directory ldb database. Any user who can write to the dnsRecord attribute over LDAP can trigger this memory corruption. By default, all authenticated LDAP users can write to the dnsRecord attribute on new DNS objects. This makes the defect a remote privilege escalation.
CVE-2016-2119 1 Samba 1 Samba 2024-11-21 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-2016-2118 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2024-11-21 6.8 MEDIUM 7.5 HIGH
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."
CVE-2016-2115 2 Canonical, Samba 2 Ubuntu Linux, Samba 2024-11-21 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-2016-2114 2 Canonical, Samba 2 Ubuntu Linux, Samba 2024-11-21 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-2016-2113 2 Canonical, Samba 2 Ubuntu Linux, Samba 2024-11-21 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.
CVE-2016-2112 2 Canonical, Samba 2 Ubuntu Linux, Samba 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
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.
CVE-2016-2111 2 Canonical, Samba 2 Ubuntu Linux, Samba 2024-11-21 4.3 MEDIUM 6.3 MEDIUM
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.
