CVE-2018-16851 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2022-08-29 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-2015-7560 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2022-08-29 4.0 MEDIUM 6.5 MEDIUM
The SMB1 implementation in smbd in Samba 3.x and 4.x before 4.1.23, 4.2.x before 4.2.9, 4.3.x before 4.3.6, and 4.4.x before 4.4.0rc4 allows remote authenticated users to modify arbitrary ACLs by using a UNIX SMB1 call to create a symlink, and then using a non-UNIX SMB1 call to write to the ACL content.
CVE-2016-2126 1 Samba 1 Samba 2022-08-29 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-2009-1888 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2022-08-29 5.8 MEDIUM N/A
The acl_group_override function in smbd/posix_acls.c in smbd in Samba 3.0.x before 3.0.35, 3.1.x and 3.2.x before 3.2.13, and 3.3.x before 3.3.6, when dos filemode is enabled, allows remote attackers to modify access control lists for files via vectors related to read access to uninitialized memory.
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-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-2017-7494 2 Debian, Samba 2 Debian Linux, Samba 2022-08-16 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-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-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-2018-16857 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-2018-16853 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-2018-16852 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-2018-14629 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.
CVE-2018-16860 2 Heimdal Project, Samba 2 Heimdal, Samba 2019-08-14 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.
