We would like to report a cache poisoning vulnerability on the OS level
DNS cache in Ubuntu. This vulnerability allows an off-path attacker to
impersonate the DNS resolver and poisons the OS-wide DNS cache directly
or through a port-preserving NAT. We have a paper describing the
problem, please see the attachment.
