                   Fedora Legacy Update Advisory

    Synopsis: Updated foomatic package fixes security vulnerability
    Advisory ID: FLSA:2076
    Issue date: 2004-11-05
    Product: Fedora Core
    Keywords: Bugfix
    Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2076
    CVE Names: CAN-2004-0801

    1. Topic:

    Updated foomatic packages that fix an arbitrary command execution
    vulnerability are now available.

    Foomatic is a comprehensive, spooler-independent database of printers,
    printer drivers, and driver descriptions.

    2. Relevent releases/architectures:

    Fedora Core 1 - i386

    3. Problem description:

    Sebastian Krahmer reported a bug in the cupsomatic and foomatic-rip
    print filters, used by the CUPS print spooler. An attacker who has
    printing access could send a carefully named file to the print server
    causing arbitrary commands to be executed as root. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2004-0801 to this issue.

    All users are advised to upgrade to these updated packages, which
    contain a backported fix 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.

    5. Bug IDs fixed:

    http://bugzilla.fedora.us - 2076 - CAN-2004-0801 - cupsomatic, foomatic
    arbitrary command execution

    6. RPMs required:

    Fedora Core 1:



    7. Verification:

    SHA1 sum Package Name


    These packages are GPG signed by Fedora Legacy for security. Our key is
    available from http://www.fedoralegacy org/about/security.php

    You can verify each package with the following command:

        rpm --checksig -v <filename>

    If you only wish to verify that each package has not been corrupted or
    tampered with, examine only the sha1sum with the following command:

        sha1sum <filename>
