Product:           Red Hat Enterprise Linux
CVE Names:         CAN-2004-1154
---------------------------------------------------------------------

1. Summary:

Updated samba packages that fix an integer overflow vulnerability are now
available for Red Hat Enterprise Linux 2.1

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

Samba provides file and printer sharing services to SMB/CIFS clients.

Greg MacManus of iDEFENSE Labs has discovered an integer overflow bug in
Samba versions prior to 3.0.10.  An authenticated remote user could exploit
this bug which may lead to arbitrary code execution on the Samba server. 
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-1154 to this issue.

Users of Samba should upgrade to these updated packages, which contain
backported security patches, and are not vulnerable to these issues.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:
