A vulnerability in PowerDNS Recursor could lead to a Denial of Service condition.
| Package | net-dns/pdns-recursor on all architectures |
|---|---|
| Affected versions | < 4.3.5 |
| Unaffected versions | >= 4.3.5 |
PowerDNS Recursor is a high-end, high-performance resolving name server.
It was discovered that it was possible to update the DNSSEC validation state to a bogus state for a cached record via DNS ANY query.
A remote attacker could send specially crafted DNS queries to deny DNSSEC validation.
There is no known workaround at this time.
All PowerDNS Recursor users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/pdns-recursor-4.3.5"
