| Package | Affected versions | Patched versions |
|---|---|---|
| nsd | ≥ 4.13.0, < 4.14.3 | 4.14.3 |
NSD from version 4.13.0 has a heap use-after-free bug in logging errors on TLS connections, causing a crash of the server process, which can be triggered trivially by sending a DNS query over a DoT connection, and closing the connection without reading the response.
