    Hi guys,

    We've been getting quite a number of suspicious HTTP traffic to our
    webservers. It seems like another network worm exploiting buffer overflow
    vulnerabilities. Attached below is a snippet of what we're getting from our
    Snort IDS. Anyone has any clue on what this is all about ?
