[ISSForum] ISS Security Brief: Microsoft SQL Slammer Worm Propagation
-----BEGIN PGP SIGNED MESSAGE-----
Internet Security Systems Security Brief
January 25, 2003
Microsoft SQL Slammer Worm Propagation
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.
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.
