Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated mailman packages close cross-site scripting vulnerability
Advisory ID: RHSA-2002:176-06
Issue date: 2002-08-12
Updated on: 2002-08-22
Product: Red Hat Linux
Keywords: mailman cross-site scripting
Cross references: RHSA-2002:177 RHSA-2002:178

CVE Names: CAN-2002-0855
- ---------------------------------------------------------------------
1. Topic:
Updated mailman packages are now available for Red Hat Linux 7.2 and 7.3.
These updates close a cross-site scripting vulnerability present in mailman
versions prior to version 2.0.12.
2. Relevant releases/architectures:
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
3. Problem description:
Mailman versions prior to 2.0.12 contain a cross-site scripting
vulnerability in the processing of invalid requests to edit a subscriber's
list subscription options.
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.
