                       Red Hat Security Advisory

    Synopsis: Updated mgetty packages available
    Advisory ID: RHSA-2003:036-01
    Issue date: 2003-04-08
    Updated on: 2003-04-08
    Product: Red Hat Linux
    Keywords: mgetty spool permission
    Cross references:
    Obsoletes: RHSA-2001:050
    CVE Names: CAN-2002-1391 CAN-2002-1392

    1. Topic:

    Updated mgetty packages are now available for Red Hat Linux 7.1,
    7.2, 7.3, and 8.0. These updates close a possible buffer overflow and a
    permissions problem present in versions of mgetty prior to version 1.1.29.

    2. Relevant releases/architectures:

    Red Hat Linux 7.1 - i386
    Red Hat Linux 7.2 - i386, ia64
    Red Hat Linux 7.3 - i386
    Red Hat Linux 8.0 - i386

    3. Problem description:

    mgetty is a getty replacement for use with data and fax modems.

    mgetty can be configured to run an external program to decide whether or
    not to answer an incoming call based on Caller ID information. Unpatched
    versions of mgetty prior to 1.1.29 would overflow an internal buffer if the
    caller name reported by the modem was too long.

    Additionally, the faxspool script supplied with versions of mgetty prior to
    1.1.29 used a simple permissions scheme to allow or deny fax transmission
    privileges. This scheme was easily circumvented because the spooling
    directory used for outgoing faxes was world-writable.

    All users of mgetty should upgrade to these errata packages, which
    contain mgetty 1.1.30 and are 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.
