Synopsis:          Updated samba packages fix security issue
Advisory ID:       RHSA-2004:498-01
Issue date:        2004-10-04
Updated on:        2004-10-04
Product:           Red Hat Enterprise Linux
CVE Names:         CAN-2004-0815
---------------------------------------------------------------------

1. Summary:

Updated samba packages that fix an input validation vulnerability are now
available.

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.

Karol Wiesek discovered an input validation issue in Samba prior to 3.0.6.
An authenticated user could send a carefully crafted request to the Samba
server, which would allow access to files outside of the configured file
share.  Note: Such files would have to be readable by the account used
for the connection.  The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0815 to this issue.

This issue does not affect Red Hat Enterprise Linux 3 as a previous erratum
updated to Samba 3.0.6 which is not vulnerable to this issue.

Users of Samba should upgrade to these updated packages, which contain an
upgrade to Samba-2.2.12, which is not vulnerable to this issue.

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:

    up2date
