Update to release 9.16.48:
Feature Changes:
* The IP addresses for B.ROOT-SERVERS.NET have been updated to
 170.247.170.2 and 2801:1b8:10::b.
Security Fixes:
* Validating DNS messages containing a lot of DNSSEC signatures
 could cause excessive CPU load, leading to a denial-of-service
 condition. This has been fixed. (CVE-2023-50387) [bsc#1219823]
* Preparing an NSEC3 closest encloser proof could cause excessive
 CPU load, leading to a denial-of-service condition. This has
 been fixed. (CVE-2023-50868) [bsc#1219826]
* Parsing DNS messages with many different names could cause
 excessive CPU load. This has been fixed. (CVE-2023-4408) [bsc#1219851]
* Specific queries could cause named to crash with an assertion
 failure when nxdomain-redirect was enabled. This has been
 fixed. (CVE-2023-5517) [bsc#1219852]
* A bad interaction between DNS64 and serve-stale could cause
 named to crash with an assertion failure, when both of these
 features were enabled. This has been fixed. (CVE-2023-5679)
 [bsc#1219853]
* Query patterns that continuously triggered cache database
 maintenance could cause an excessive amount of memory to be
 allocated, exceeding max-cache-size and potentially leading to
 all available memory on the host running named being exhausted.
 This has been fixed. (CVE-2023-6516) [bsc#1219854]
Removed Features:
* Support for using AES as the DNS COOKIE algorithm
 (cookie-algorithm aes,) has been deprecated and will be removed
 in a future release. Please use the current default,
 SipHash-2-4, instead.");
