Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated samba packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 3, 4, and 5, and Red Hat Enterprise Linux 4.7, 5.3, and 5.4 Extended Update Support.

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)

For Red Hat Enterprise Linux 4, this update also fixes the following bug :

* Previously, the restorecon utility was required during the installation of the samba-common package. As a result, attempting to update samba without this utility installed may have failed with the following error :

/var/tmp/rpm-tmp.[xxxxx]: line 7: restorecon: command not found

With this update, the utility is only used when it is already present on the system, and the package is now always updated as expected.
(BZ#629602)

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

Solution

Update the affected samba packages.
