     pdns-recursor was updated to 4.6.6:

  * fixes deterred spoofing attempts can lead to authoritative servers being
       marked unavailable (boo#1209897, CVE-2023-26437)

     Fixes in 4.6.5:

  * When an expired NSEC3 entry is seen, move it to the front
       of the expiry queue

  * Log invalid RPZ content when obtained via IXFR

  * Detect invalid bytes in makeBytesFromHex()

  * Timeout handling for IXFRs as a client

     Fixes in 4.6.4:

  * Check qperq limit if throttling happened, as it increases counters

  * Failure to retrieve DNSKEYs of an Insecure zone should not be fatal

  * Resize answer length to actual received length in udpQueryResponse");
