|---|---|---|---|---|---|
| CVE-2018-16851 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service. | |||||
| CVE-2018-10858 | 4 Canonical, Debian, Redhat and 1 more | 8 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 5 more | 2024-02-04 | 6.5 MEDIUM | 8.8 HIGH |
| A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable. | |||||
| CVE-2017-12151 | 4 Debian, Hp, Redhat and 1 more | 8 Debian Linux, Cifs Server, Enterprise Linux and 5 more | 2024-02-04 | 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-2018-10918 | 2 Canonical, Samba | 2 Ubuntu Linux, Samba | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| A null pointer dereference flaw was found in the way samba checked database outputs from the LDB database layer. An authenticated attacker could use this flaw to crash a samba server in an Active Directory Domain Controller configuration. Samba versions before 4.7.9 and 4.8.4 are vulnerable. | |||||
| CVE-2018-16857 | 1 Samba | 1 Samba | 2024-02-04 | 4.3 MEDIUM | 5.9 MEDIUM |
| Samba from version 4.9.0 and before version 4.9.3 that have AD DC configurations watching for bad passwords (to restrict brute forcing of passwords) in a window of more than 3 minutes may not watch for bad passwords at all. The primary risk from this issue is with regards to domains that have been upgraded from Samba 4.8 and earlier. In these cases the manual testing done to confirm an organisation's password policies apply as expected may not have been re-done after the upgrade. | |||||
| CVE-2017-12150 | 3 Debian, Redhat, Samba | 7 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 4 more | 2024-02-04 | 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-2018-10919 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| The Samba Active Directory LDAP server was vulnerable to an information disclosure flaw because of missing access control checks. An authenticated attacker could use this flaw to extract confidential attribute values using LDAP search expressions. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable. | |||||
| CVE-2018-1140 | 1 Samba | 1 Samba | 2024-02-04 | 3.3 LOW | 6.5 MEDIUM |
| A missing input sanitization flaw was found in the implementation of LDP database used for the LDAP server. An attacker could use this flaw to cause a denial of service against a samba server, used as a Active Directory Domain Controller. All versions of Samba from 4.8.0 onwards are vulnerable | |||||
| CVE-2018-16841 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the KDC process. | |||||
| CVE-2017-2619 | 3 Debian, Redhat, Samba | 3 Debian Linux, Enterprise Linux, Samba | 2024-02-04 | 6.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2018-1050 | 4 Canonical, Debian, Redhat and 1 more | 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more | 2024-02-04 | 3.3 LOW | 4.3 MEDIUM |
| 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. | |||||
| CVE-2018-1057 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-02-04 | 6.5 MEDIUM | 8.8 HIGH |
| 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). | |||||
| CVE-2017-11103 | 5 Apple, Debian, Freebsd and 2 more | 6 Iphone Os, Mac Os X, Debian Linux and 3 more | 2024-02-04 | 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-2017-14746 | 4 Canonical, Debian, Redhat and 1 more | 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more | 2024-02-04 | 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-2017-9461 | 3 Debian, Redhat, Samba | 8 Debian Linux, Enterprise Linux Desktop, Enterprise Linux Server and 5 more | 2024-02-04 | 6.8 MEDIUM | 6.5 MEDIUM |
| 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. | |||||
| CVE-2017-15275 | 4 Canonical, Debian, Redhat and 1 more | 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more | 2024-02-04 | 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-2017-7494 | 2 Debian, Samba | 2 Debian Linux, Samba | 2024-02-04 | 10.0 HIGH | 9.8 CRITICAL |
| 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. | |||||
| CVE-2016-2126 | 1 Samba | 1 Samba | 2024-02-04 | 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-2016-2119 | 1 Samba | 1 Samba | 2024-02-04 | 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-2015-5296 | 1 Samba | 1 Samba | 2024-02-04 | 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. | |||||
