| CVE-2018-1139 | 3 Canonical, Redhat, Samba | 7 Ubuntu Linux, Enterprise Linux, Enterprise Linux Desktop and 4 more | 2024-08-05 | 8.1 High |
| A flaw was found in the way samba before 4.7.9 and 4.8.4 allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled. A man-in-the-middle attacker could use this flaw to read the credential and other details passed between the samba server and client. | ||||
| CVE-2018-1140 | 1 Samba | 1 Samba | 2024-08-05 | N/A |
| 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-2018-1057 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-08-05 | 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-2019-19344 | 4 Canonical, Opensuse, Samba and 1 more | 7 Ubuntu Linux, Leap, Samba and 4 more | 2024-08-05 | 6.5 Medium |
| There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer. | ||||
| CVE-2019-14907 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2024-08-05 | 6.5 Medium |
| All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless). | ||||
| CVE-2019-14902 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-08-05 | 5.4 Medium |
| There is an issue in all samba 4.11.x versions before 4.11.5, all samba 4.10.x versions before 4.10.12 and all samba 4.9.x versions before 4.9.18, where the removal of the right to create or modify a subtree would not automatically be taken away on all domain controllers. | ||||
| CVE-2019-14833 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2024-08-05 | 5.4 Medium |
| A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks. | ||||
| CVE-2019-14861 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-08-05 | 5.3 Medium |
| All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the (poorly named) dnsserver RPC pipe provides administrative facilities to modify DNS records and zones. Samba, when acting as an AD DC, stores DNS records in LDAP. In AD, the default permissions on the DNS partition allow creation of new records by authenticated users. This is used for example to allow machines to self-register in DNS. If a DNS record was created that case-insensitively matched the name of the zone, the ldb_qsort() and dns_name_compare() routines could be confused into reading memory prior to the list of DNS entries when responding to DnssrvEnumRecords() or DnssrvEnumRecords2() and so following invalid memory as a pointer. | ||||
| CVE-2019-14870 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-08-05 | 5.4 Medium |
| All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set. | ||||
| CVE-2019-14847 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2024-08-05 | 4.9 Medium |
| A flaw was found in samba 4.0.0 before samba 4.9.15 and samba 4.10.x before 4.10.10. An attacker can crash AD DC LDAP server via dirsync resulting in denial of service. Privilege escalation is not possible with this issue. | ||||
| CVE-2019-12435 | 1 Samba | 1 Samba | 2024-08-04 | N/A |
| Samba 4.9.x before 4.9.9 and 4.10.x before 4.10.5 has a NULL pointer dereference, leading to Denial of Service. This is related to the AD DC DNS management server (dnsserver) RPC server process. | ||||
| CVE-2019-12436 | 2 Canonical, Samba | 2 Ubuntu Linux, Samba | 2024-08-04 | N/A |
| Samba 4.10.x before 4.10.5 has a NULL pointer dereference, leading to an AD DC LDAP server Denial of Service. This is related to an attacker using the paged search control. The attacker must have directory read access in order to attempt an exploit. | ||||
| CVE-2019-10218 | 3 Fedoraproject, Redhat, Samba | 4 Fedora, Enterprise Linux, Storage and 1 more | 2024-08-04 | 6.5 Medium |
| A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user. | ||||
| CVE-2019-10197 | 4 Canonical, Debian, Redhat and 1 more | 5 Ubuntu Linux, Debian Linux, Enterprise Linux and 2 more | 2024-08-04 | N/A |
| A flaw was found in samba versions 4.9.x up to 4.9.13, samba 4.10.x up to 4.10.8 and samba 4.11.x up to 4.11.0rc3, when certain parameters were set in the samba configuration file. An unauthenticated attacker could use this flaw to escape the shared directory and access the contents of directories outside the share. | ||||
| CVE-2019-3870 | 3 Fedoraproject, Samba, Synology | 9 Fedora, Samba, Directory Server and 6 more | 2024-08-04 | 6.1 Medium |
| A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8. Within this directory, files are created with mode 0666, which is world-writable, including a sample krb5.conf, and the list of DNS names and servicePrincipalName values to update. | ||||
| CVE-2019-3824 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-08-04 | N/A |
| A flaw was found in the way an LDAP search expression could crash the shared LDAP server process of a samba AD DC in samba before version 4.10. An authenticated user, having read permissions on the LDAP server, could use this flaw to cause denial of service. | ||||
| CVE-2019-3880 | 5 Debian, Fedoraproject, Opensuse and 2 more | 7 Debian Linux, Fedora, Leap and 4 more | 2024-08-04 | 5.4 Medium |
| A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable. | ||||
| CVE-2020-27840 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Samba | 2024-08-04 | 7.5 High |
| A flaw was found in samba. Spaces used in a string around a domain name (DN), while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2020-25718 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-08-04 | 8.8 High |
| A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC (read-only domain controller). This would allow an RODC to print administrator tickets. | ||||
| CVE-2020-25721 | 1 Samba | 1 Samba | 2024-08-04 | 8.8 High |
| Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets. | ||||
