            <title>[GODRIVER-1417] Add fuzzer tests to the BSON package(s)</title>
                <link>https://jira.mongodb.org/browse/GODRIVER-1417</link>
                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-color: #cccccc;border-style: dashed;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;border-bottom-style: dashed;border-bottom-color: #cccccc;background-color: #239eb0;&quot;&gt;&lt;b&gt;Epic Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;
&lt;p&gt;There have been a few cases already of cases where the BSON code used by the driver is a little too happy-path oriented. Invalid BSON or documents seem to have a high chance of triggering panics or otherwise erroneous behavior.&lt;/p&gt;

&lt;p&gt;Me and &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=divjot.arora&quot; class=&quot;user-hover&quot; rel=&quot;divjot.arora&quot;&gt;divjot.arora&lt;/a&gt; at some point investigated some issues in the BSON code for handling invalid documents that were sent by another user&apos;s fuzz testing of a library using the driver. And &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=craig.wilson%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;craig.wilson@mongodb.com&quot;&gt;craig.wilson@mongodb.com&lt;/a&gt; has found a case where a negative length causes a panic in validation code.&lt;/p&gt;

&lt;p&gt;In general, it seems like what we need is a fuzzer to more systematically find all of these edge cases and increase the robustness of the BSON package.&lt;/p&gt;

&lt;p&gt;Implementing a fuzzer for BSON &lt;em&gt;should&lt;/em&gt; (who knows, really) be easy to write for BSON, since it is just a lump of bytes.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Documentation&quot;&gt;&lt;/a&gt;Documentation&lt;/h4&gt;
&lt;p&gt;&lt;span class=&quot;error&quot;&gt;&amp;#91;Scope Document|&amp;#93;&lt;/span&gt;&lt;br/&gt;
&lt;span class=&quot;error&quot;&gt;&amp;#91;Technical Design Document|&amp;#93;&lt;/span&gt;&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;</description>
