Synopsis: Critical: samba security update Issue date: 2007-11-15 CVE Names: CVE-2007-4572 CVE-2007-4138 CVE-2007-5398 A buffer overflow flaw was found in the way Samba creates NetBIOS replies. If a Samba server is configured to run as a WINS server, a remote unauthenticated user could cause the Samba server to crash or execute arbitrary code. (CVE-2007-5398) A heap based buffer overflow flaw was found in the way Samba authenticates users. A remote unauthenticated user could trigger this flaw to cause the Samba server to crash. Careful analysis of this flaw has determined that arbitrary code execution is not possible, and under most circumstances will not result in a crash of the Samba server. (CVE-2007-4572) A flaw was found in the way Samba assigned group IDs under certain conditions. If the "winbind nss info" parameter in smb.conf is set to either "sfu" or "rfc2307", Samba users are incorrectly assigned the group ID of 0.
