Description

From Red Hat Security Advisory 2010:0488 :

Updated samba and samba3x packages that fix one security issue 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.

An input sanitization flaw was found in the way Samba parsed client data. A malicious client could send a specially crafted SMB packet to the Samba server, resulting in arbitrary code execution with the privileges of the Samba server (smbd). (CVE-2010-2063)

Red Hat would like to thank the Samba team for responsibly reporting this issue. Upstream acknowledges Jun Mao as the original reporter.

Users of Samba are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, the smb service will be restarted automatically.
