Red Hat Security Advisory

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
