Red Hat Security Advisory

Synopsis: Updated samba packages fix security issues
Advisory ID: RHSA-2004:632-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2004-632.html
Issue date: 2004-11-16
Updated on: 2004-11-16
Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-0882 CAN-2004-0930
----------------------------------------------------------------------

1. Summary:

Updated samba packages that fix various security vulnerabilities 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
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, ppc64, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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

During a code audit, Stefan Esser discovered a buffer overflow in Samba versions prior to 3.0.8 when handling unicode filenames. An authenticated remote user could exploit this bug which may lead to arbitrary code execution on the server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0882 to this issue. Red Hat believes that the Exec-Shield technology (enabled by default since Update 3) will block attempts to remotely exploit this vulnerability on x86 architectures.

Additionally, a bug was found in the input validation routines in versions of Samba prior to 3.0.8 that caused the smbd process to consume abnormal amounts of system memory. An authenticated remote user could exploit this bug to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0930 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:

up2date

For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system:

http://www.redhat.com/docs/manuals/enterprise/

5. Bug IDs fixed (http://bugzilla.redhat.com/ for more info):

138325 - CAN-2004-0930 wildcard remote DoS
134640 - CAN-2004-0882 unicode parsing overflow
