    Synopsis: Updated NetPBM packages fix multiple temporary file vulnerabilities
    Advisory ID: RHSA-2004:030-01
    Issue date: 2004-02-05
    Updated on: 2004-02-05
    Product: Red Hat Linux
    Keywords: symlink tmpfile tmp

    Obsoletes:
    CVE Names: CAN-2003-0924
    - ---------------------------------------------------------------------

    1. Topic:

    Updated NetPBM packages are available that fix a number of temporary file
    vulnerabilities in the netpbm libraries.

    2. Relevant releases/architectures:

    Red Hat Linux 9 - i386

    3. Problem description:

    The netpbm package contains a library of functions that support
    programs for handling various graphics file formats, including .pbm
    (portable bitmaps), .pgm (portable graymaps), .pnm (portable anymaps),
    .ppm (portable pixmaps), and others.

    A number of temporary file bugs have been found in versions of NetPBM.
    These could allow a local user the ability to overwrite or create files as
    a different user who happens to run one of the the vulnerable utilities.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) has
    assigned the name CAN-2003-0924 to this issue.

    Users are advised to upgrade to the erratum packages, which contain patches
    from Debian that correct these bugs.

    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.

    If up2date fails to connect to Red Hat Network due to SSL Certificate
    Errors, you need to install a version of the up2date client with an updated
    certificate. The latest version of up2date is available from the Red Hat
    FTP site and may also be downloaded directly from the RHN website:

    https://rhn.redhat.com/help/latest-up2date.pxt

    5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

    113842 - CAN-2003-0924 netpbm temporary file vulnerabilities

    6. RPMs required:

    Red Hat Linux 9:

    SRPMS:
    ftp://updates.redhat.com/9/en/os/SRPMS/netpbm-9.24-10.90.1.src.rpm

    i386:

    These packages are GPG signed by Red Hat for security. Our key is
    available from https://www.redhat.com/security/keys.html

    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>
