      <title>CVE-2021-32765 — Integer Overflow to Buffer Overflow in Hiredis</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2021-32765</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; redis hiredis&lt;/p&gt;
&lt;p&gt;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&amp;#39;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.&lt;/p&gt;</description>
