    Strategic Reconnisiance Team Security Advisory(SRT2001-03)
    Topic: SCO 5.0.6 MMDF issues (deliver)
    Vendor: SCO
    Release Date: 03/27/01
    ======================================================================
    .: Description
    SCO OpenServer 5.0.6 ships with a previously known buggy MMDF package.
    SCO Security Bulletin 2000.06 states "Recently Network Associates, Inc.
    issued a SECURITY ADVISORY against all versions of MMDF prior to the
    beta release 2.44a-B4" however SCO still released OpenServer 5.0.6 with
    version 2.43.3b of MMDF. deliver has poor processing of command line arguments
    resulting in a buffer overflow /opt/K/SCO/MMDF/2.43.3b/usr/mmdf/bin/deliver
    will core dump if fed more than 4085 chars.

    .: Impact
    /opt/K/SCO/MMDF/2.43.3b/usr/mmdf/bin/deliver `perl -e 'print "A" x 5000'`
    Memory fault - core dumped

    This problem makes it possible to overwrite memory space of the running
    process,
    and potentially execute code with the inherited privileges of root.

    .: Workaround
    chmod -s /opt/K/SCO/MMDF/2.43.3b/usr/mmdf/bin/deliver

    .: Systems Affected
    SCO OpenServer 5.0.6 upgrade from 5.0.x and 5.0.6 fresh install.

    .: Proof of Concept
    To be released at a later time.

    .: Vendor Status
    Vendor was notified on 03/22/01. Vendor lab tests confirmed the issue. Patch
    status is unknown.
