CVE-2013-6442
Description
From CVE.org
The owner_set function in smbcacls.c in smbcacls in Samba 4.0.x before 4.0.16 and 4.1.x before 4.1.6 removes an ACL during use of a --chown or --chgrp option, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging an unintended administrative change.

Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
