      <title>CVE-2025-40777 — A possible assertion failure when 'stale-answer-client-timeout' is set to '0'</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-40777</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; ISC BIND 9&lt;/p&gt;
&lt;p&gt;If a `named` caching resolver is configured with `serve-stale-enable` `yes`, and with `stale-answer-client-timeout` set to `0` (the only allowable value other than `disabled`), and if the resolver, in the process of resolving a query, encounters a CNAME chain involving a specific combination of cached or authoritative records, the daemon will abort with an assertion failure.
This issue affects BIND 9 versions 9.20.0 through 9.20.10, 9.21.0 through 9.21.9, and 9.20.9-S1 through 9.20.10-S1.&lt;/p&gt;</description>

      <title>USN-7641-1 — bind9 vulnerability</title>
      <link>https://vulnerability.circl.lu/vuln/usn-7641-1</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Ubuntu:25.04: bind9&lt;/p&gt;
&lt;p&gt;It was discovered that Bind incorrectly handled configurations where the
stale-answer-client-timeout option is set to 0. A remote attacker could
possibly use this issue to cause Bind to crash, resulting in a denial of
service.&lt;/p&gt;</description>
