                       Red Hat, Inc. Red Hat Security Advisory

    Synopsis: gftp format string vulnerability corrected
    Advisory ID: RHSA-2001:053-06
    Issue date: 2001-04-20
    Updated on: 2001-04-23
    Product: Red Hat Linux
    Keywords: gftp format

    ---------------------------------------------------------------------

    1. Topic:

    An updated gftp package is available for Red Hat Linux 6.2 and 7.1. This
    package contains an upgrade to gftp version 2.0.8, which improves
    functionality and fixes a format string vulnerability.

    2. Relevant releases/architectures:

    Red Hat Linux 6.2 - alpha, i386, sparc

    Red Hat Linux 7.0 - alpha, i386

    Red Hat Linux 7.1 - i386

    3. Problem description:

    Previous gftp versions had a problem with format strings allowing malicious
    ftp servers to potentially execute code on the gftp user's system.

    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):
