+
+<p>It was discovered that there was an integer-overflow vulnerability in
+hiredis, a C client library for communicating with Redis databases.  This
+occurred within the handling and parsing of 'multi-bulk' replies.</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-32765">CVE-2021-32765</a>
+
+    <p>Hiredis is a minimalistic C client library for the Redis database. In
+    affected versions Hiredis is vulnurable to integer overflow if provided
+    maliciously crafted or corrupted `RESP` `mult-bulk` protocol data. When
+    parsing `multi-bulk` (array-like) replies, hiredis fails to check if `count
+    * sizeof(redisReply*)` can be represented in `SIZE_MAX`. If it can not, and
+    the `calloc()` call doesn't itself make this check, it would result in a
+    short allocation and subsequent buffer overflow. Users of hiredis who are
+    unable to update may set the
+    [maxelements](https://github.com/redis/hiredis#reader-max-array-elements)
+    context option to a value small enough that no overflow is
+    possible.</p></li>
+
+</ul>
+
+<p>For Debian 9 <q>Stretch</q>, these problems have been fixed in version
+0.13.3-1+deb9u1.</p>
+
+<p>We recommend that you upgrade your hiredis packages.</p>
+
+<p>Further information about Debian LTS security advisories, how to apply
+these updates to your system and frequently asked questions can be
