+<p>Two vunerabilities were discovered in c-ares, an asynchronous name
+resolver library:</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2023-31130">CVE-2023-31130</a>
+
+    <p>ares_inet_net_pton() is found to be vulnerable to a buffer underflow
+    for certain ipv6 addresses, in particular "0::00:00:00/2" was found
+    to cause an issue. c-ares only uses this function internally for
+    configuration purposes, however external usage for other purposes may
+    cause more severe issues.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2023-32067">CVE-2023-32067</a>
+
+    <p>Target resolver may erroneously interprets a malformed UDP packet
+    with a lenght of 0 as a graceful shutdown of the connection, which
+    could cause a denial of service.</p></li>
+
+</ul>
+
+<p>For the stable distribution (bullseye), these problems have been fixed in
+version 1.17.1-1+deb11u3.</p>
+
+<p>We recommend that you upgrade your c-ares packages.</p>
+
