1. Topic:

Updated Mailman packages are now available for Red Hat Linux 7.2.  These
updates fix cross-site scripting bugs which might allow another server to
be used to gain a user's private information from a server running Mailman.

2. Relevant releases/architectures:

Red Hat Linux 7.2 - i386

3. Problem description:

A server running Mailmain versions prior to 2.0.8 will send certain
user-modifiable data to clients without escaping embedded tags.  This data
may contain scripts which will then be executed by an unwary client,
possibly transmitting private information to a third party.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2001-0884 to this issue.

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.

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

tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg
