Description Tomas Hoger 2008-09-08 15:31:16 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-3905 to the following vulnerability:

resolv.rb in Ruby 1.8.5 and earlier, 1.8.6 before 1.8.6-p287, 1.8.7
before 1.8.7-p72, and 1.9 r18423 and earlier uses sequential
transaction IDs and constant source ports for DNS requests, which
makes it easier for remote attackers to spoof DNS responses, a
different vulnerability than CVE-2008-1447.
