<blockquote>
<h2>0.7.3</h2>
<p>This release fixes a number of decoding issues that can lead to
panics on invalid input data. They have been assigned
CVE-2023-39914.</p>
<p>Bug fixes</p>
<ul>
<li>Fixes various decoding that lead to a panic on invalid data.
Specifically:
<ul>
<li>error out rather than panic when a nested value has a greater length
than allowed by the outer value,</li>
<li>check that there is enough data available before skipping over a
primitive value’s content,</li>
<li>check that enough data is available before trying to parse a tag
value,</li>
<li>check for correct encoding of bit strings: don’t allow the number of
unused bits to be greater than 7 and that they are zero for an empty bit
string,</li>
<li>check for correct encoding of object identifiers: they cannot be
empty and the last byte must have bit 7 cleared.</li>
</ul>
</li>
</ul>
