"From Red Hat Security Advisory 2010:0860 :

Updated samba packages that fix one security issue are now available
for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
critical security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

Samba is a suite of programs used by machines to share files,
printers, and other information.

A missing array boundary checking flaw was found in the way Samba
parsed the binary representation of Windows security identifiers
(SIDs). A malicious client could send a specially crafted SMB request
to the Samba server, resulting in arbitrary code execution with the
privileges of the Samba server (smbd). (CVE-2010-3069)

Users of Samba are advised to upgrade to these updated packages, which
correct this issue. After installing this update, the smb service will
be restarted automatically.");
