Description

A vulnerability has been found and corrected in samba :

Samba 3.x before 3.6.20, 4.0.x before 4.0.11, and 4.1.x before 4.1.1, when vfs_streams_depot or vfs_streams_xattr is enabled, allows remote attackers to bypass intended file restrictions by leveraging ACL differences between a file and an associated alternate data stream (ADS) (CVE-2013-4475).

The updated packages has been upgraded to the 3.6.20 version which resolves various upstream bugs and is not vulnerable to this issue.
