| CVE | Sev | CVSS | KEV | Affected versions | Fixed in | Published | Description |
|---|---|---|---|---|---|---|---|
| CVE-2022-32744 | Hig | 8.8 | < 4.16.4+git.297.1497eb221ed-1.1 | 4.16.4+git.297.1497eb221ed-1.1 | Aug 25, 2022 | A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling full domain takeover. | |
| CVE-2022-32742 | Med | 4.3 | < 4.16.4+git.297.1497eb221ed-1.1 | 4.16.4+git.297.1497eb221ed-1.1 | Aug 25, 2022 | A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control | |
| CVE-2022-2031 | Hig | 8.8 | < 4.16.4+git.297.1497eb221ed-1.1 | 4.16.4+git.297.1497eb221ed-1.1 | Aug 25, 2022 | A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other's tickets. A user who has been requested to change their password, can exploit this flaw to obtain and use tic | |
| CVE-2020-25721 | Hig | 8.8 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Mar 16, 2022 | 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 | Hig | 8.8 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Mar 2, 2022 | 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 credent | |
| CVE-2021-23192 | Hig | 7.5 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Mar 2, 2022 | 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-2021-44141 | Med | 4.3 | < 4.15.5+git.328.f1f29505d84-1.1 | 4.15.5+git.328.f1f29505d84-1.1 | Feb 21, 2022 | 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 | |
| CVE-2021-44142 | Hig | 8.8 | < 4.15.5+git.328.f1f29505d84-1.1 | 4.15.5+git.328.f1f29505d84-1.1 | Feb 21, 2022 | 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-bou | |
| CVE-2020-25722 | Hig | 8.8 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Feb 18, 2022 | 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-2020-25719 | Hig | 7.2 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Feb 18, 2022 | 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 withi | |
| CVE-2020-25718 | Hig | 8.8 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Feb 18, 2022 | 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-2020-25717 | Hig | 8.1 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Feb 18, 2022 | 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 | Med | 5.9 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Feb 18, 2022 | 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-2020-27840 | Hig | 7.5 | < 4.14.6+git.182.2205d5224e3-1.1 | 4.14.6+git.182.2205d5224e3-1.1 | May 12, 2021 | 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 syst | |
| CVE-2021-20277 | Hig | 7.5 | < 4.14.6+git.182.2205d5224e3-1.1 | 4.14.6+git.182.2205d5224e3-1.1 | May 12, 2021 | 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-2021-20254 | Med | 6.8 | < 4.14.6+git.182.2205d5224e3-1.1 | 4.14.6+git.182.2205d5224e3-1.1 | May 5, 2021 | 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 t | |
| CVE-2020-14318 | Med | 4.3 | < 4.14.6+git.182.2205d5224e3-1.1 | 4.14.6+git.182.2205d5224e3-1.1 | Dec 3, 2020 | 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-2020-14383 | Med | 6.5 | < 4.14.6+git.182.2205d5224e3-1.1 | 4.14.6+git.182.2205d5224e3-1.1 | Dec 2, 2020 | 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 | |
| CVE-2020-17049 | Med | 6.6 | < 4.15.2+git.193.a4d6307f1fd-1.1 | 4.15.2+git.193.a4d6307f1fd-1.1 | Nov 11, 2020 | A security feature bypass vulnerability exists in the way Key Distribution Center (KDC) determines if a service ticket can be used for delegation via Kerberos Constrained Delegation (KCD). To exploit the vulnerability, a compromised service that is configured to use KCD could tam | |
| CVE-2020-14323 | Med | 5.5 | < 4.14.6+git.182.2205d5224e3-1.1 | 4.14.6+git.182.2205d5224e3-1.1 | Oct 29, 2020 | A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before 4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of service. |
