1. Topic:

New Samba packages are available for Red Hat Linux 5.2, 6.2, 7, and 7.1.
These packages fix a security problem with remote clients giving special
NetBIOS names to the server.

It is recommended that all Samba users upgrade to the fixed packages.
Please note that the packages for Red Hat Linux 6.2 require an updated
logrotate package.

UPDATE: The packages for Red Hat Linux 5.2 have been updated. The original
packages detected the availability of syscalls present in kernels newer
than 2.2. Red Hat Linux 5.2 has a 2.0 kernel, and users will experience
various problems when these syscalls are used. This release removes the
detection of these syscalls from the autoconf script.

2. Problem description:

The Samba configuration used in Red Hat Linux logs operations into
[remotenetbiosname].log. By sending an invalid NetBIOS name, Samba could be
fooled to write its log in unintended and inappropriate locations. This can
be especially dangerous if combined with a symlink created by a local user.

3. Bug IDs fixed: (see bugzilla for more information)

45645 - Log settings in configuration file allow system compromise
46109 - Problem with samba after an update

4. Relevant releases/architectures:

Red Hat Linux 5.2 - alpha, i386, sparc
Red Hat Linux 6.2 - alpha, i386, sparc
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - alpha, i386

5. RPMs required:

6. 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.

These packages are GPG signed by Red Hat, Inc. for security. Our key is available at:

You can verify each package with the following command: rpm --checksig filename

If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: rpm --checksig --nogpg filename

Note that you need RPM >= 3.0 to check GnuPG keys.
