Overview

org.graylog2:graylog2-server is a log management platform.

Affected versions of this package are vulnerable to Insecure Randomness such that an external attacker could inject forged DNS responses into a Graylog's lookup table cache. Graylog seems to bind a single socket for outgoing DNS queries. That socket is bound to a random port number which is not changed again.
