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

    


    
        <h2>Description:</h2>
    
    <p>This update for bind fixes the following issues:</p>
<p>Update to 9.16.50:</p>
<ul>
<li>Bug Fixes:</li>
<li>A regression in cache-cleaning code enabled memory use to grow
    significantly more quickly than before, until the configured
    max-cache-size limit was reached. This has been fixed.</li>
<li>Using rndc flush inadvertently caused cache cleaning to become
    less effective. This could ultimately lead to the configured
    max-cache-size limit being exceeded and has now been fixed.</li>
<li>The logic for cleaning up expired cached DNS records was
    tweaked to be more aggressive. This change helps with enforcing
    max-cache-ttl and max-ncache-ttl in a timely manner.</li>
<li>It was possible to trigger a use-after-free assertion when the
    overmem cache cleaning was initiated. This has been fixed.
  New Features:</li>
<li>Added RESOLVER.ARPA to the built in empty zones.</li>
<li>Security Fixes:</li>
<li>It is possible to craft excessively large numbers of resource
    record types for a given owner name, which has the effect of
    slowing down database processing. This has been addressed by
    adding a configurable limit to the number of records that can
    be stored per name and type in a cache or zone database. The
    default is 100, which can be tuned with the new
    max-types-per-name option. (CVE-2024-1737, bsc#1228256)</li>
<li>Validating DNS messages signed using the SIG(0) protocol (RFC
    2931) could cause excessive CPU load, leading to a
    denial-of-service condition. Support for SIG(0) message
    validation was removed from this version of named.
    (CVE-2024-1975, bsc#1228257)</li>
<li>When looking up the NS records of parent zones as part of
    looking up DS records, it was possible for named to trigger an
    assertion failure if serve-stale was enabled. This has been
    fixed. (CVE-2024-4076, bsc#1228258)</li>
</ul>
