01 Aug 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. Se ha encontrado un fallo en Samba. Los usuarios de AD de Samba pueden hacer que el servidor acceda a datos no inicializados con una solicitud de adición o modificación de LDAP, resultando usualmente en un fallo de segmentación. It was discovered that Samba did not handle MaxQueryDuration when being used in AD DC configurations, contra... • https://security.gentoo.org/glsa/202309-06 • CWE-125: Out-of-bounds Read CWE-908: Use of Uninitialized Resource •

01 Aug 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 userAccountControl. Se ha encontrado un fallo en el servidor LDAP de Samba AD.

10 May 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. Se ha encontrado un fallo en la forma en que Samba maneja los metadatos de los archivos/directorios. Este fallo permite a un atacante autenticado con permisos para leer o modificar los metadatos del recurso compartido, llevar a cabo esta operación fuera del recurso compartido.

21 Feb 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 attack to succeed.

01 Feb 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-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.

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 •
