| A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. | |||||
| CVE-2016-2124 | 5 Canonical, Debian, Fedoraproject and 2 more | 24 Ubuntu Linux, Debian Linux, Fedora and 21 more | 2023-12-10 | 4.3 MEDIUM | 5.9 MEDIUM |

| CVE-2020-25721 | 1 Samba | 1 Samba | 2023-12-10 | 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-2021-44142 | 6 Canonical, Debian, Fedoraproject and 3 more | 23 Ubuntu Linux, Debian Linux, Fedora and 20 more | 2023-12-10 | 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-2021-23192 | 1 Samba | 1 Samba | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements. | |||||
| CVE-2021-3738 | 1 Samba | 1 Samba | 2023-12-10 | 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-2020-25718 | 2 Fedoraproject, Samba | 2 Fedora, Samba | 2023-12-10 | 6.5 MEDIUM | 8.8 HIGH |
| A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC (read-only domain controller). This would allow an RODC to print administrator tickets. | |||||
| CVE-2020-25722 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-12-10 | 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-2021-43566 | 1 Samba | 1 Samba | 2023-12-10 | 1.2 LOW | 2.5 LOW |
| All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to allow a directory to be created in an area of the server file system not exported under the share definition. Note that SMB1 has to be enabled, or the share also available via NFS in order for this attack to succeed. | |||||
| CVE-2021-3671 | 3 Debian, Netapp, Samba | 5 Debian Linux, Management Services For Element Software, Management Services For Netapp Hci and 2 more | 2023-12-10 | 4.0 MEDIUM | 6.5 MEDIUM |
| A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server. | |||||
| CVE-2021-20254 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2023-12-10 | 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-2021-20277 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Samba | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in Samba's libldb. Multiple, consecutive leading spaces in an LDAP attribute can lead to an out-of-bounds memory write, leading to a crash of the LDAP server process handling the request. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2020-27840 | 3 Debian, Fedoraproject, Samba | 3 Debian Linux, Fedora, Samba | 2023-12-10 | 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-2020-10730 | 5 Debian, Fedoraproject, Opensuse and 2 more | 5 Debian Linux, Fedora, Leap and 2 more | 2023-12-10 | 4.0 MEDIUM | 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. | |||||
