    It's not always obvious that an archive shouldn't be trusted --
    for example, the breakins at the BSD and Sendmail sites.
    
    Trusting directory traversal strings (absolute paths and ../) should
    require an explicit request on the part of the user. Just because a
    user 'should' be wary of a trojan archive doesn't mean that they
    always will be.

    Powerful committed communication, reaching through fear, uncertainty and
    doubt to touch the jewel within each person and bring it to life.
