RHSA-2007:1016: samba security update



Updated samba packages that fix several security issues are now available for Red Hat Enterprise Linux 4. This update has been rated as having critical security impact by the Red Hat Security Response Team.

Samba is a suite of programs used by machines to share files, printers, and other information. 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. (CVE-2007-4138) Red Hat would like to thank Alin Rad Pop of Secunia Research, Rick King, and the Samba developers for responsibly disclosing these issues. All Samba users are advised to upgrade to these updated packages, which contain a backported patch to correct these issues.
