## Description:

This update for bind fixes the following issues:

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.
