| CVE-2019-10218 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2024-02-04 | 4.3 MEDIUM | 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-2019-14870 | 3 Canonical, Fedoraproject, Samba | 3 Ubuntu Linux, Fedora, Samba | 2024-02-04 | 6.4 MEDIUM | 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-2019-19344 | 4 Canonical, Opensuse, Samba and 1 more | 7 Ubuntu Linux, Leap, Samba and 4 more | 2024-02-04 | 4.0 MEDIUM | 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-2011-3585 | 2 Redhat, Samba | 2 Enterprise Linux, Samba | 2024-02-04 | 1.9 LOW | 4.7 MEDIUM |
| Multiple race conditions in the (1) mount.cifs and (2) umount.cifs programs in Samba 3.6 allow local users to cause a denial of service (mounting outage) via a SIGKILL signal during a time window when the /etc/mtab~ file exists. | |||||
| CVE-2019-14907 | 5 Canonical, Fedoraproject, Redhat and 2 more | 9 Ubuntu Linux, Fedora, Enterprise Linux and 6 more | 2024-02-04 | 2.6 LOW | 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 | 3 Canonical, Opensuse, Samba | 3 Ubuntu Linux, Leap, Samba | 2024-02-04 | 5.5 MEDIUM | 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-2019-14847 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2024-02-04 | 4.0 MEDIUM | 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-2019-12436 | 2 Canonical, Samba | 2 Ubuntu Linux, Samba | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| 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-2019-3870 | 3 Fedoraproject, Samba, Synology | 9 Fedora, Samba, Directory Server and 6 more | 2024-02-04 | 3.6 LOW | 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 | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| 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 | 6 Debian Linux, Fedora, Leap and 3 more | 2024-02-04 | 5.5 MEDIUM | 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-2019-12435 | 1 Samba | 1 Samba | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| 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-2019-10197 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-02-04 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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-2018-16860 | 2 Heimdal Project, Samba | 2 Heimdal, Samba | 2024-02-04 | 6.0 MEDIUM | 7.5 HIGH |
| 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-2018-16853 | 1 Samba | 1 Samba | 2024-02-04 | 4.3 MEDIUM | 5.9 MEDIUM |
| Samba from version 4.7.0 has a vulnerability that allows a user in a Samba AD domain to crash the KDC when Samba is built in the non-default MIT Kerberos configuration. With this advisory the Samba Team clarify that the MIT Kerberos build of the Samba AD DC is considered experimental. Therefore the Samba Team will not issue security patches for this configuration. Additionally, Samba 4.7.12, 4.8.7 and 4.9.3 have been issued as security releases to prevent building of the AD DC with MIT Kerberos unless --with-experimental-mit-ad-dc is specified to the configure command. | |||||
| CVE-2017-12163 | 3 Debian, Redhat, Samba | 7 Debian Linux, Enterprise Linux, Enterprise Linux Desktop and 4 more | 2024-02-04 | 4.8 MEDIUM | 7.1 HIGH |
| 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-2018-1139 | 3 Canonical, Redhat, Samba | 5 Ubuntu Linux, Enterprise Linux Desktop, Enterprise Linux Server and 2 more | 2024-02-04 | 4.3 MEDIUM | 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-2016-2125 | 2 Redhat, Samba | 8 Enterprise Linux Desktop, Enterprise Linux Server, Enterprise Linux Server Aus and 5 more | 2024-02-04 | 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-2018-14629 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| A denial of service vulnerability was discovered in Samba's LDAP server before versions 4.7.12, 4.8.7, and 4.9.3. A CNAME loop could lead to infinite recursion in the server. An unprivileged local attacker could create such an entry, leading to denial of service. | |||||
| CVE-2018-16852 | 1 Samba | 1 Samba | 2024-02-04 | 3.5 LOW | 4.4 MEDIUM |
| Samba from version 4.9.0 and before version 4.9.3 is vulnerable to a NULL pointer de-reference. During the processing of an DNS zone in the DNS management DCE/RPC server, the internal DNS server or the Samba DLZ plugin for BIND9, if the DSPROPERTY_ZONE_MASTER_SERVERS property or DSPROPERTY_ZONE_SCAVENGING_SERVERS property is set, the server will follow a NULL pointer and terminate. There is no further vulnerability associated with this issue, merely a denial of service. | |||||
