MSNBC on Linux worms for BIND 4.9.7 / 8.2.2 or earlier:


�IT SEEMS TO be a variant of the Ramen worm, said David Dittrich, 
security administrator for the University of Washington and an expert 
on digital forensics and hacking tools. The Ramen worm, which used 
three well-known security flaws to infect systems using the Red Hat 
distribution of Linux, hit in mid-January and infected an unknown 
number of computers. The vulnerabilities exploited by Ramen occur in 
three programs shipped with most Linux distributions and installed by 
default. The 1i0n worm, discovered last month by the Systems 
Administration Networking and Security Institute (SANS), used a 
fourth flaw to spread among servers that had domain name service, or 
DNS, software installed.


FINDING FLAWS

The Adore worm�also known as the Red worm�uses all four flaws to 
automatically break into vulnerable systems. While patches have 
existed for all the vulnerabilities for at least a few months, most 
system administrators have not patched their systems, said Matt 
Fearnow, incident handler for the SANS Global Incident Analysis Center.
