01 Feb 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 that account, such as one added when a computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding an SPN that matches an existing service.

11 Jan 2022 — 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.

11 Nov 2021 — 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 t... • https://bugzilla.redhat.com/show_bug.cgi?id=2021726 • CWE-416: Use After Free •

CVSS: 6.8EPSS: 0%CPEs: 8EXPL: 0CVE-2021-20254 – samba: Negative idmap cache entries can cause incorrect group entries in the Samba file server process token
https://notcve.org/view.php?id=CVE-2021-20254
30 Apr 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 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. • https://bugzilla.redhat.com/show_bug.cgi?id=1949442 • CWE-125: Out-of-bounds Read •
