RHSA-2004:019 - Security Advisory

Topic

Updated mailman packages that close a DoS vulnerability present in mailman
versions prior to version 2.1 are now available.

Description

Mailman is a mailing list manager.

Matthew Galgoci of Red Hat discovered a Denial of Service (DoS)
vulnerability in versions of Mailman prior to 2.1. An attacker could send
a carefully-crafted message causing mailman to crash. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0991 to this issue.

Users of Mailman are advised to upgrade to the erratum packages, which
include a backported security fix and are not vulnerable to this issue.

Red Hat would like to thank Barry Warsaw for providing a patch for this issue.

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.
