                   Fedora Legacy Update Advisory

    Synopsis: Updated mailman package fixes security issue
    Advisory ID: FLSA:152895
    Issue date: 2005-07-10
    Product: Red Hat Linux, Fedora Core
    Keywords: Bugfix
    CVE Names: CAN-2005-0202
    ---------------------------------------------------------------------

    ---------------------------------------------------------------------
    1. Topic:

    Updated mailman packages that correct a mailman security issue are now
    available.

    Mailman is software to help manage email discussion lists, much like
    Majordomo and Smartmail.

    2. Relevant releases/architectures:

    Red Hat Linux 7.3 - i386
    Red Hat Linux 9 - i386
    Fedora Core 1 - i386

    3. Problem description:

    A flaw in the true_path function of Mailman was discovered. A remote
    attacker who is a member of a private mailman list could use a carefully
    crafted URL and gain access to arbitrary files on the server. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2005-0202 to this issue.

    Note: Mailman installations running on Apache 2.0-based servers are not
    vulnerable to this issue.

    Users of mailman should update to these erratum packages that contain a
    patch and are not vulnerable 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 yum and apt. Many
    people find this an easier way to apply updates. To use yum issue:

    yum update

    or to use apt:

    apt-get update; apt-get upgrade

    This will start an interactive process that will result in the
    appropriate RPMs being upgraded on your system. This assumes that you
    have yum or apt-get configured for obtaining Fedora Legacy content.
    Please visit http://www.fedoralegacy.org/docs for directions on how to
    configure yum and apt-get.

    tampered with, examine only the sha1sum with the following command:

        sha1sum <filename>
