ACL Removal Vulnerability in Samba 4.0.x and 4.1.x

CVE-2013-6442 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:N

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.
