Although unlikely in many setups, an external attacker could inject forged DNS responses into a Graylog's lookup table cache. In order to prevent cache poisoning with spoofed DNS responses, it is necessary to maximise the uncertainty in the choice of a source port for a DNS query. This goes against recommended practice since 2008, when Dan Kaminsky discovered how easy is to carry out DNS cache poisoning attacks. Graylog binds a single socket for outgoing DNS queries and while that socket is bound to a random port number it is never changed again. Graylog makes use of only one single source port for DNS queries. The Installer is available for immediate download from the Installer homepage.Graylog is a free and open log management platform.
