samba security update

CentOS Errata and Security Advisory CESA-2007:1114-01

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

A stack buffer overflow flaw was found in the way Samba authenticates
remote users. A remote unauthenticated user could trigger this flaw to
cause the Samba server to crash, or execute arbitrary code with the
permissions of the Samba server. (CVE-2007-6015)

Red Hat would like to thank Alin Rad Pop of Secunia Research for
responsibly disclosing this issue.

This update also fixes a regression caused by the fix for CVE-2007-4572,
which prevented some clients from being able to properly access shares.

Users of Samba are advised to upgrade to these updated packages, which
contain a backported patch to resolve these issues.
