Updated CVS packages available

Updated cvs packages are now available for Red Hat Linux 6.2, 7, 7.1, 7.2,
7.3, and 8.0. These updates close a vulnerability which would permit
arbitrary command execution on servers configured to allow anonymous
read-only access.

[Updated 16 April 2003]
Added packages for Red Hat Linux on IBM iSeries and pSeries systems

CVS is a version control system frequently used to manage source code
repositories. During an audit of the CVS sources, Stefan Esser
discovered an exploitable double-free bug in the CVS server.

On servers which are configured to allow anonymous read-only access, this
bug could be used by anonymous users to gain write privileges. Users with
CVS write privileges can then use the Update-prog and Checkin-prog features
to execute arbitrary commands on the server.

All users of CVS are advised to upgrade to these erratum packages which
contain patches to correct the double-free bug.

Our thanks go to Stefan Esser of e-matters for reporting this issue to us.

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.
