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

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

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.
