                   Fedora Legacy Update Advisory

    Synopsis: Updated sysstat packages fix security vulnerabilities
    Advisory ID: FLSA:1372
    Issue date: 2004-10-03
    Product: Red Hat Linux
    Keywords: Bugfix
    Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=1372
    CVE Names: CAN-2004-0107
    ------------------------------------------------------------------------

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

    Updated sysstat packages that fix various bugs and a minor security
    issue are now available.

    Sysstat is a tool for gathering system statistics.

    2. Relevent releases/architectures:

    Red Hat Linux 7.3 - i386

    3. Problem description:

    A bug was found in the Red Hat sysstat package post and trigger scripts,
    which used insecure temporary file names. A local attacker could
    overwrite system files using carefully-crafted symbolic links in the
    /tmp directory. The Common Vulnerabilities and Exposures project
    (cve.mitre.org) has assigned the name CAN-2004-0107 to this issue.

    Other issues addressed in this advisory include:

    * iostat -x should return all partitions on the system (up to a maximum
    of 1024)

    * sar should handle network device names with more than 8 characters
    properly

    Users of sysstat should upgrade to these updated packages, which
    contain patches to correct 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 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 - bug #1372

    6. RPMs required:

    Red Hat Linux 7.3:

    SRPM:
    http://download.fedoralegacy.org/redhat/7.3/updates/SRPMS/sysstat-4.0.3-4.legacy.src.rpm

    i386:
    http://download.fedoralegacy.org/redhat/7.3/updates/i386/sysstat-4.0.3-4.legacy.i386.rpm

    7. Verification:

    SHA1 sum Package Name
    ----------------------------------------------------------------------------

    b2d1ced29b39cd024169b173d01db6fa99327bfb
    7.3/updates/i386/sysstat-4.0.3-4.legacy.i386.rpm
    5bd937c2c0d643ba5a4dcab9c1f5ded2d67c9fb5
    7.3/updates/SRPMS/sysstat-4.0.3-4.legacy.src.rpm

    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>
