Description
The SMB2 implementation in Samba 3.6.x before 3.6.6, as used on the IBM Storwize V7000 Unified 1.3 before 1.3.2.3 and 1.4 before 1.4.0.1 and possibly other products, does not properly enforce CIFS share attributes, which allows remote authenticated users to (1) write to a read-only share; (2) trigger data-integrity problems related to the oplock, locking, coherency, or leases attribute; or (3) have an unspecified impact by leveraging incorrect handling of the browseable or "hide unreadable" parameter.
