+<p>Multiple vulnerabilities have been discovered in OpenSSL, a Secure
+Sockets Layer toolkit.</p>
+
+<ul>

+<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-3711">CVE-2021-3711</a>
+
+    <p>John Ouyang reported a buffer overflow vulnerability in the SM2
+    decryption. An attacker able to present SM2 content for
+    decryption to an application can take advantage of this flaw to
+    change application behaviour or cause the application to crash
+    (denial of service).</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-3712">CVE-2021-3712</a>
+
+    <p>Ingo Schwarze reported a buffer overrun flaw when processing ASN.1
+    strings in the X509_aux_print() function, which can result in denial
+    of service.</p>
+
+<p>Additional details can be found in the upstream advisory:
+<a href="https://www.openssl.org/news/secadv/20210824.txt">https://www.openssl.org/news/secadv/20210824.txt</a></p></li>
+
+</ul>
+
+<p>For the oldstable distribution (buster), these problems have been fixed
+in version 1.1.1d-0+deb10u7.</p>
+
+<p>For the stable distribution (bullseye), these problems have been fixed in
+version 1.1.1k-1+deb11u1.</p>
+
+<p>We recommend that you upgrade your openssl packages.</p>
