Detail
| 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. |

| Title: | RHSA-2014:0383: samba4 security update (Moderate) | ||
| Description: | Samba is an open-source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information. It was found that certain Samba configurations did not enforce the password lockout mechanism. A remote attacker could use this flaw to perform password guessing attacks on Samba user accounts. Note: this flaw only affected Samba when deployed as a Primary Domain Controller. (CVE-2013-4496) A flaw was found in Samba's "smbcacls" command, which is used to set or get ACLs on SMB file shares. Certain command line options of this command would incorrectly remove an ACL previously applied on a file or a directory, leaving the file or directory without the intended ACL. (CVE-2013-6442) A flaw was found in the way the pam_winbind module handled configurations that specified a non-existent group as required. An authenticated user could possibly use this flaw to gain access to a service using pam_winbind in its PAM configuration when group restriction was intended for access to the service. (CVE-2012-6150) Red Hat would like to thank the Samba project for reporting CVE-2013-4496 and CVE-2013-6442, and Sam Richardson for reporting CVE-2012-6150. Upstream acknowledges Andrew Bartlett as the original reporter of CVE-2013-4496, and Noel Power as the original reporter of CVE-2013-6442. All users of Samba are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the smb service will be restarted automatically. | ||
