    1. Topic:

    Updated SquirrelMail packages are now available for Red Hat Linux.

    2. Relevant releases/architectures:

    Red Hat Linux 8.0 - noarch
    Red Hat Linux 9 - noarch

    3. Problem description:

    SquirrelMail is a webmail package written in PHP. Multiple vulnerabilities
    have been found which affect versions of SquirrelMail shipped with Red Hat
    Linux 8.0 and Red Hat Linux 9.

    Cross-site scripting vulnerabilities in SquirrelMail version 1.2.10 and
    earlier allow remote attackers to execute script as other Web users via
    mailbox displays, message displays, or search results displays. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
    CAN-2003-0160 to these issues.

    All users are advised to upgrade to these errata packages containing
    SquirrelMail version 1.2.11, which is not vulnerable to these issues.

    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):

    85860 - Cannot view or download attachments.

    6. RPMs required:

    Red Hat Linux 8.0:

    SRPMS:
    ftp://updates.redhat.com/8.0/en/os/SRPMS/squirrelmail-1.2.11-1.src.rpm

    noarch:
    ftp://updates.redhat.com/8.0/en/os/noarch/squirrelmail-1.2.11-1.noarch.rpm

    Red Hat Linux 9:

    SRPMS:
    ftp://updates.redhat.com/9/en/os/SRPMS/squirrelmail-1.2.11-1.src.rpm

    noarch:
    ftp://updates.redhat.com/9/en/os/noarch/squirrelmail-1.2.11-1.noarch.rpm

    7. Verification:

    MD5 sum Package Name

    c1b724beae51115074af0f605ebf2482 9/en/os/noarch/squirrelmail-1.2.11-1.noarch.rpm

    These packages are GPG signed by Red Hat for security. Our key is
    available at http://www.redhat.com/solutions/security/news/publickey/

    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 md5sum with the following command:
        
        md5sum <filename>
