    <p>An update that solves six vulnerabilities can now be installed.</p>

    


    
        <h2>Description:</h2>
    
    <p>This update for bind fixes the following issues:</p>
<p>Update to release 9.16.48:</p>
<p>Feature Changes:
* The IP addresses for B.ROOT-SERVERS.NET have been updated to
  170.247.170.2 and 2801:1b8:10::b.</p>
<p>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]</p>
<p>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.</p>
