Doc Text: |
A flaw was found in the bind package which may result in a Denial of Service in `named` process. This is a result of a reachable assertion, leading `named` to prematurely terminate when both conditions are met: nxdomain-redirect for the queried domain is configured and the resolver receives a PTR query, used for a reverse DNS lookup, for a RFC 1918 address that would normally result in an authoritative `NXDOMAIN` response. A single query matching both conditions can lead to a Denial of Service in the named application.
