    running Lighttpd tries to access a file with a mtime of 0.
  
Impact :

    A remote attacker could upload a specially crafted file to the server
    or send a specially crafted request and then abort the connection,
    possibly resulting in a crash or a Denial of Service by CPU
    consumption.
