Overview

Bind vulnerability


Packages

Details

Michael Sinatra discovered that Bind did not correctly validate certain
records added to its cache. When DNSSEC validation is in use, a remote
attacker could exploit this to spoof DNS entries and poison DNS caches.
Among other things, this could lead to misdirected email and web traffic.
