CVE-1999-0810 1 Samba 1 Samba 2022-08-17 10.0 HIGH N/A
Denial of service in Samba NETBIOS name service daemon (nmbd).
CVE-1999-0812 1 Samba 1 Samba 2022-08-17 7.6 HIGH N/A
Race condition in Samba smbmnt allows local users to mount file systems in arbitrary locations.
CVE-2017-14746 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2022-08-16 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-2020-25721 1 Samba 1 Samba 2022-03-22 6.5 MEDIUM 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.
CVE-2021-3738 1 Samba 1 Samba 2022-03-10 6.5 MEDIUM 8.8 HIGH
In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access.
CVE-2020-25722 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2022-02-25 6.5 MEDIUM 8.8 HIGH
Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored data. An attacker could use this flaw to cause total domain compromise.
CVE-2020-25717 5 Canonical, Debian, Fedoraproject and 2 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2022-02-25 8.5 HIGH 8.1 HIGH
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
CVE-2016-2124 5 Canonical, Debian, Fedoraproject and 2 more 24 Ubuntu Linux, Debian Linux, Fedora and 21 more 2022-02-25 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-2021-44141 3 Fedoraproject, Redhat, Samba 3 Fedora, Storage, Samba 2022-02-23 3.5 LOW 4.3 MEDIUM
All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed.
CVE-2019-3824 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2020-08-24 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-2017-11103 5 Apple, Debian, Freebsd and 2 more 6 Iphone Os, Mac Os X, Debian Linux and 3 more 2020-08-18 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-2018-1140 1 Samba 1 Samba 2019-10-09 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-2018-16852 1 Samba 1 Samba 2019-10-09 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.
CVE-2018-16853 1 Samba 1 Samba 2019-10-09 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-2018-16857 1 Samba 1 Samba 2019-10-09 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-2018-14629 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2019-10-09 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-2018-10919 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2019-10-09 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-2018-10918 2 Canonical, Samba 2 Ubuntu Linux, Samba 2019-10-09 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-2017-12151 4 Debian, Hp, Redhat and 1 more 8 Debian Linux, Cifs Server, Enterprise Linux and 5 more 2019-10-09 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-2011-2411 2 Hp, Samba 3 Nonstop Server, Nonstop Server Software, Samba 2019-10-09 9.0 HIGH N/A
Unspecified vulnerability on HP NonStop Servers with software H06.x through H06.23.00 and J06.x through J06.12.00, when Samba is used, allows remote authenticated users to execute arbitrary code via unknown vectors.
