Description

CentOS Errata and Security Advisory CESA-2007:1013-01

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)

Red Hat would like to thank Alin Rad Pop of Secunia Research, and the Samba developers for responsibly disclosing these issues.

Users of Samba are advised to ugprade to these updated packages, which contain backported patches to resolve these issues.
