    For those interested, NGSS has just published a paper describing how to
    defeat the mechanism built into Windows 2003 Server to prevent exploitation
    of stack based buffer overflow vulnerabilities. Previous work done in this
    area presented methods that only worked in highly specific scenarios - the
    new methods presented in this paper are generic. The paper can be downloaded
    from http://www.nextgenss.com/papers/defeating-w2k3-stack-protection.pdf .
