                        SCO Security Advisory

Subject:                OpenLinux: mgetty caller ID buffer overflow and spool perm vulnerabilities
Advisory number:        CSSA-2003-021.0
Issue date:             2003 May 13
Cross reference:

1. Problem Description

        mgetty will overflow an internal buffer if the caller name
        reported by the modem is too long.

        The faxspool spooling directory used for outgoing faxes was
        world-writable.


2. Vulnerable Supported Versions

        System                          Package
        ----------------------------------------------------------------------

        OpenLinux 3.1.1 Server          prior to mgetty-1.1.22_Aug17-13.i386.rpm

        OpenLinux 3.1.1 Workstation     prior to mgetty-1.1.22_Aug17-13.i386.rpm


3. Solution

        The proper solution is to install the latest packages. Many
        customers find it easier to use the Caldera System Updater, called
        cupdate (or kcupdate under the KDE environment), to update these
        packages rather than downloading and installing them by hand.
