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. (CVE-2007-4138)
