    CVE-2013-6442

    Published: 14 Mar 2014Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
