Title:	Samba 3.0.0 <= 4.3.2 Bypass File-Access Restrictions Vulnerability (CVE-2015-5252)
Summary:	Insufficient symlink verification could allow data access; outside share path.
Description:	Summary: Insufficient symlink verification could allow data access outside share path. Vulnerability Insight: All versions of Samba from 3.0.0 to 4.3.2 inclusive are vulnerable to a bug in symlink verification, which under certain circumstances could allow client access to files outside the exported share path. If a Samba share is configured with a path that shares a common path prefix with another directory on the file system, the smbd daemon may allow the client to follow a symlink pointing to a file or directory in that other directory, even if the share parameter 'wide links' is set to 'no' (the default). Affected Software/OS: Samba versions 3.0.0 through 4.1.21, 4.2.0 through 4.2.6 and 4.3.0 through 4.3.2. Solution: Update to version 4.1.22, 4.2.7, 4.3.3 or later. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
