                    Fedora Legacy Update Advisory

    Synopsis: Updated zip package fixes security issue
    Advisory ID: FLSA:2255
    Issue date: 2005-02-01
    Product: Red Hat Linux, Fedora Core
    Keywords: Bugfix
    Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2255
    CVE Names: CAN-2004-1010
    ---------------------------------------------------------------------

    1. Topic:

    An updated zip package that fixes a buffer overflow vulnerability is now
    available.

    The zip program is an archiving utility which can create ZIP-compatible
    archives.

    2. Relevant releases/architectures:

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

    3. Problem description:

    A buffer overflow bug has been discovered in zip when handling long file
    names. An attacker could create a specially crafted path which could
    cause zip to crash or execute arbitrary instructions. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2004-1010 to this issue.

    Users of zip should upgrade to this updated package, which contains
    backported patches and is 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.
