Description
A flaw in query-handling code can cause `named` to exit prematurely with an assertion failure when:

- `nxdomain-redirect <domain>;` is configured, and
- the resolver receives a PTR query for an RFC 1918 address that would normally result in an authoritative NXDOMAIN response.
This issue affects BIND 9 versions 9.12.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.

Remediation

Vendor Solution

Upgrade to the patched release most closely related to your current version of BIND 9: 9.16.48, 9.18.24, 9.19.21, 9.16.48-S1, or 9.18.24-S1.


Vendor Workaround

Disabling the `nxdomain-redirect` feature makes the faulty code path impossible to reach, preventing this flaw from being exploitable.
