|---|---|---|---|---|---|---|---|
| CVE-2022-0336 | — | < 4.15.4+git.324.8332acf1a63-150300.3.25.3 | 4.15.4+git.324.8332acf1a63-150300.3.25.3 | Aug 29, 2022 | The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an account modification re-adds an SPN that was previously present on tha | ||
| CVE-2022-32746 | — | < 4.15.8+git.500.d5910280cc7-150300.3.37.1 | 4.15.8+git.500.d5910280cc7-150300.3.37.1 | Aug 25, 2022 | A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP message values freed by a preceding database module, resulting in a use-after-free issue. This issue is only possible when modifying certain privileged attributes, such as userAc | ||
| CVE-2022-32745 | — | < 4.15.8+git.500.d5910280cc7-150300.3.37.1 | 4.15.8+git.500.d5910280cc7-150300.3.37.1 | Aug 25, 2022 | A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP add or modify the request, usually resulting in a segmentation fault. | ||
| CVE-2022-32744 | — | < 4.15.8+git.500.d5910280cc7-150300.3.37.1 | 4.15.8+git.500.d5910280cc7-150300.3.37.1 | 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 | — | < 4.15.8+git.500.d5910280cc7-150300.3.37.1 | 4.15.8+git.500.d5910280cc7-150300.3.37.1 | 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 | — | < 4.15.8+git.500.d5910280cc7-150300.3.37.1 | 4.15.8+git.500.d5910280cc7-150300.3.37.1 | 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-2021-20316 | — | < 4.15.4+git.324.8332acf1a63-150300.3.25.3 | 4.15.4+git.324.8332acf1a63-150300.3.25.3 | Aug 23, 2022 | A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated attacker with permissions to read or modify share metadata, to perform this operation outside of the share. | ||
| CVE-2020-25721 | — | < 4.13.13+git.528.140935f8d6a-3.12.1 | 4.13.13+git.528.140935f8d6a-3.12.1 | 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 | — | < 4.13.13+git.528.140935f8d6a-3.12.1 | 4.13.13+git.528.140935f8d6a-3.12.1 | 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'.
