    Secunia Research has discovered a vulnerability in Mozilla / Mozilla
    Firefox, which can be exploited to spoof the source displayed in the
    Download Dialog box.

    The problem is that long sub-domains and paths aren't displayed
    correctly, which therefore can be exploited to obfuscate what is
    being displayed in the source field of the Download Dialog box.

    The vulnerability has been confirmed in Mozilla 1.7.3 for Linux and
    Mozilla Firefox 1.0.
