Descriptions

The (1) CreateAccount, (2) OpenAccount, (3) AddAccountRights, and (4) RemoveAccountRights LSA RPC procedures in smbd in Samba 3.4.x before 3.4.17, 3.5.x before 3.5.15, and 3.6.x before 3.6.5 do not properly restrict modifications to the privileges database, which allows remote authenticated users to obtain the "take ownership" privilege via an LSA connection.

El (1) CreateAccount, (2) OpenAccount, (3) AddAccountRights, y (4) RemoveAccountRights LSA RPC procedimientos en smbd de Samba v3.4.x anterior a v3.4.17, v3.5.x anterior a v3.5.15 y v3.6.x anterior a v3.6.5 no restringe correctamente las modificaciones en la base de datos de privilegios, permitiendo a usuarios remotos autenticados obtener la "toma de posesión" de privilegios a través de una conexión LSA.

Samba is an open-source implementation of the Server Message Block or Common Internet File System protocol, which allows PC-compatible machines to share files, printers, and other information. A flaw was found in the way Samba handled certain Local Security Authority Remote Procedure Calls. An authenticated user could use this flaw to issue an RPC call that would modify the privileges database on the Samba server, allowing them to steal the ownership of files and directories that are being shared by the Samba server, and create, delete, and modify user accounts, as well as other Samba server administration tasks.
