    Microsoft SQL Slammer Worm Propagation
    
    Synopsis:
    
    ISS X-Force has learned of a worm that is spreading via Microsoft SQL
    servers. The worm is responsible for large amounts of Internet traffic
    as 
    well as millions of UDP/IP probes at the time of this alert's
    publication. 
    This worm attempts to exploit MS/SQL servers vulnerable to the SQL
    Server 
    Resolution service buffer overflow (CVE CAN-2002-0649). Once a
    vulnerable 
    computer is compromised, the worm will infect that target, randomly
    select a 
    new target, and resend the exploit and propagation code to that host.
    
    Impact:
    
    Although the Slammer worm is not destructive to the infected host, it
    does generate a damaging level of network traffic when it scans for
    additional 
    targets.  A large amount of network traffic is created by the worm,
    which 
    scans random IP addresses for vulnerable servers.
