1. Topic:

Updated Samba packages are now available to fix security vulnerabilities
found during a code audit.

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 is a suite of utilities which provides file and printer sharing
services to SMB/CIFS clients.

Sebastian Krahmer discovered a security vulnerability present
in unpatched versions of Samba prior to 2.2.8. An anonymous user could use
the vulnerability to gain root access on the target machine.=20

Additionally, a race condition could allow an attacker to overwrite
critical system files.

All users of Samba are advised to update to the erratum packages which
contain patches to correct these vulnerabilities.

These packages contain the security fixes backported to the Samba 2.2.7
codebase.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
