| CVE-2020-14303 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2022-04-28 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in the AD DC NBT server in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4. A samba user could send an empty UDP packet to cause the samba server to crash. | |||||
| CVE-2020-1472 | 8 Canonical, Debian, Fedoraproject and 5 more | 11 Ubuntu Linux, Debian Linux, Fedora and 8 more | 2022-04-26 | 9.3 HIGH | 10.0 CRITICAL |
| An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC), aka 'Netlogon Elevation of Privilege Vulnerability'. | |||||
| CVE-2019-3870 | 3 Fedoraproject, Samba, Synology | 9 Fedora, Samba, Directory Server and 6 more | 2022-04-19 | 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-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-2021-44142 | 6 Canonical, Debian, Fedoraproject and 3 more | 23 Ubuntu Linux, Debian Linux, Fedora and 20 more | 2022-02-23 | 9.0 HIGH | 8.8 HIGH |
| The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. | |||||
| 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-2020-14318 | 2 Redhat, Samba | 3 Enterprise Linux, Storage, Samba | 2022-01-01 | 4.0 MEDIUM | 4.3 MEDIUM |
| A flaw was found in the way samba handled file and directory permissions. An authenticated user could use this flaw to gain access to certain file and directory information which otherwise would be unavailable to the attacker. | |||||
| CVE-2021-20254 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2021-06-24 | 4.9 MEDIUM | 6.8 MEDIUM |
| A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity. | |||||
| CVE-2019-14907 | 5 Canonical, Fedoraproject, Redhat and 2 more | 9 Ubuntu Linux, Fedora, Enterprise Linux and 6 more | 2021-05-29 | 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-2019-10218 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2021-05-29 | 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-2019-14833 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2021-05-29 | 4.9 MEDIUM | 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-2019-14847 | 3 Fedoraproject, Opensuse, Samba | 3 Fedora, Leap, Samba | 2021-05-29 | 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-2020-27840 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Samba | 2021-05-26 | 5.0 MEDIUM | 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-2020-14383 | 2 Redhat, Samba | 2 Enterprise Linux, Samba | 2021-05-05 | 4.0 MEDIUM | 6.5 MEDIUM |
| A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate, but many RPC services will not. | |||||
| CVE-2020-10760 | 4 Canonical, Fedoraproject, Opensuse and 1 more | 4 Ubuntu Linux, Fedora, Leap and 1 more | 2020-11-22 | 4.0 MEDIUM | 6.5 MEDIUM |
| A use-after-free flaw was found in all samba LDAP server versions before 4.10.17, before 4.11.11, before 4.12.4 used in a AC DC configuration. A Samba LDAP user could use this flaw to crash samba. | |||||
| 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. | |||||
