<blockquote>
<p><strong>Symmetrically encrypting large values can lead to integer overflow</strong></p>
<h3>Impact</h3>
<p>When certain sequences of <code>update()</code> calls with large values (multiple GBs) for symetric encryption or decryption occur, it's possible for an integer overflow to happen, leading to mishandling of buffers.</p>
<h3>Patches</h3>
<p>This is patched in version 3.3.2 and newer.</p>
