| CVE-2020-10730 | 5 Debian, Fedoraproject, Opensuse and 2 more | 6 Debian Linux, Fedora, Leap and 3 more | 2024-11-21 | 6.5 Medium |
| A NULL pointer dereference, or possible use-after-free flaw was found in Samba AD LDAP server in versions before 4.10.17, before 4.11.11 and before 4.12.4. Although some versions of Samba shipped with Red Hat Enterprise Linux do not support Samba in AD mode, the affected code is shipped with the libldb package. This flaw allows an authenticated user to possibly trigger a use-after-free or NULL pointer dereference. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2020-10704 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Leap and 1 more | 2024-11-21 | 7.5 High |
| A flaw was found when using samba as an Active Directory Domain Controller. Due to the way samba handles certain requests as an Active Directory Domain Controller LDAP server, an unauthorized user can cause a stack overflow leading to a denial of service. The highest threat from this vulnerability is to system availability. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2. | ||||
| CVE-2020-10700 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2024-11-21 | 5.3 Medium |
| A use-after-free flaw was found in the way samba AD DC LDAP servers, handled 'Paged Results' control is combined with the 'ASQ' control. A malicious user in a samba AD could use this flaw to cause denial of service. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2. | ||||
| CVE-2019-3880 | 5 Debian, Fedoraproject, Opensuse and 2 more | 7 Debian Linux, Fedora, Leap and 4 more | 2024-11-21 | 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-2019-3824 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-11-21 | 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-2019-14902 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-11-21 | 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-2019-14870 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 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-2019-14861 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 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-2019-14847 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2024-11-21 | 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-2019-14833 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2024-11-21 | 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-2019-12436 | 2 Canonical, Samba | 2 Ubuntu Linux, Samba | 2024-11-21 | 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-2019-12435 | 1 Samba | 1 Samba | 2024-11-21 | 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-2019-10218 | 3 Fedoraproject, Redhat, Samba | 4 Fedora, Enterprise Linux, Storage and 1 more | 2024-11-21 | 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 | 2024-11-21 | 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-2018-1140 | 1 Samba | 1 Samba | 2024-11-21 | 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-2018-1139 | 3 Canonical, Redhat, Samba | 7 Ubuntu Linux, Enterprise Linux, Enterprise Linux Desktop and 4 more | 2024-11-21 | 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-2018-1057 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-11-21 | 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-2018-1050 | 4 Canonical, Debian, Redhat and 1 more | 8 Ubuntu Linux, Debian Linux, Enterprise Linux and 5 more | 2024-11-21 | 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-2018-16860 | 2 Heimdal Project, Samba | 2 Heimdal, Samba | 2024-11-21 | N/A |
| A flaw was found in samba's Heimdal KDC implementation, versions 4.8.x up to, excluding 4.8.12, 4.9.x up to, excluding 4.9.8 and 4.10.x up to, excluding 4.10.3, when used in AD DC mode. A man in the middle attacker could use this flaw to intercept the request to the KDC and replace the user name (principal) in the request with any desired user name (principal) that exists in the KDC effectively obtaining a ticket for that principal. | ||||
| CVE-2018-16857 | 1 Samba | 1 Samba | 2024-11-21 | N/A |
| 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. | ||||
