Título:	Samba 3.4.0 <= 3.6.4 Elevate Privileges Vulnerability (CVE-2012-2111)
Resumen:	Samba 3.4.x to 3.6.4 are affected by a vulnerability that allows; arbitrary users to modify privileges on a file server.
Descripción:	Summary: Samba 3.4.x to 3.6.4 are affected by a vulnerability that allows arbitrary users to modify privileges on a file server. Vulnerability Insight: Samba versions 3.4.x to 3.6.4 inclusive are affected by a vulnerability that allows arbitrary users to modify privileges on a file server. Security checks were incorrectly applied to the Local Security Authority (LSA) remote procedure calls (RPC) CreateAccount, OpenAccount, AddAccountRights and RemoveAccountRights allowing any authenticated user to modify the privileges database. This is a serious error, as it means that authenticated users can connect to the LSA and grant themselves the 'take ownership' privilege. This privilege is used by the smbd file server to grant the ability to change ownership of a file or directory which means users could take ownership of files or directories they do not own. Affected Software/OS: Samba versions 3.4.0 through 3.4.16, 3.5.0 through 3.5.14 and 3.6.0 through 3.6.4. Solution: Update to 3.4.17, 3.5.15, 3.6.5 or later. CVSS Score: 6.5 CVSS Vector: AV:N/AC:L/Au:S/C:P/I:P/A:P
