Detailsinfo

A vulnerability was found in Samba up to 3.6.5 (File Transfer Software). It has been declared as problematic. This vulnerability affects an unknown code of the component SMB2 Implementation. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-264. As an impact it is known to affect integrity. CVE summarizes:

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.

The weakness was disclosed 02/19/2013 by Ulf Troppens with IBM Corporation as confirmed bulletin (Website). The advisory is shared for download at ibm.com.
