CVE-2026-50248
CVE-2026-50248 affects NLnet Labs Unbound 1.7.0 through 1.25.1. When an auth/rpz zone has a configured primary hostname that resolves to a bogus A/AAAA, it can still be treated as a possible XFR endpoint. A malicious actor who can spoof the hostname’s A/AAAA (no valid RRSIG required) may become t...

Uncaught Exception
Overview Affected versions of this package are vulnerable to Uncaught Exception in the transfer. An attacker can cause a panic and disrupt DNS service availability by sending an AXFR request to a zone configured with k8sexternal headless-service zone transfers when a headless service endpoint...
CVE-2026-12244
A flaw was found in nsd. When nsd is configured as a secondary server for a zone, a remote attacker, acting as the primary server for that zone, can send a specially crafted DNS message within an AXFR Asynchronous Full Zone Transfer request. This message, containing a malformed SVCB Service Bindi...
USN-8474-1: NSD vulnerabilities
It was discovered that NSD incorrectly handled APL resource records with an address length larger than permitted for the address family. A remote attacker could use this to cause a stack-based buffer overflow when the zone is written to disk, potentially executing arbitrary code with the privileg...
CVE-2026-40209
An attacker might be able to cause outgoing TCP connections to backend to be stuck until a timeout occurs instead of being released immediately, by sending IXFR queries. This could be used to cause a denial of service if there is a limit to the number of concurrent connections to this backend, or...
CVE-2026-40209 Denial of service via IXFR queries
An attacker might be able to cause outgoing TCP connections to backend to be stuck until a timeout occurs instead of being released immediately, by sending IXFR queries. This could be used to cause a denial of service if there is a limit to the number of concurrent connections to this backend, or...

CVE-2026-12490
When a provide-xfr is given with a tls-auth-name, a secondary requesting a transfer should provide a client certificate with that name. However, no client certificate is needed when the request comes in over TLS over the regular tls-port and not the tls-auth-port or over over TCP over the regular...
