<p dir="auto">I think there are various levels of fuzzying for this project.</p>
<ol dir="auto">
<li>Input to be decoded by DER and BER decoders - <code>asn1_der_decoding2</code>
</li>
<li>Input to simple BER and DER decoders - <code>asn1_decode_simple_d/ber</code>, <code>asn1_length_d/ber</code>
</li>
<li>Input to the ASN.1 parser <code>asn1_parser2tree</code>
</li>
<li>Intermediate input from <code>asn1_parser2array</code> to <code>asn1_array2tree</code>
</li>
</ol>
<p dir="auto">To my understanding from what you write above what you are fuzzying is 4. That is, you are trying to make the <code>asn1_array2tree</code> strong even if the intermediate input from <code>asn1_parser2array</code> is maliciously modified right? I wouldn't say these are not important, but for a first phase, I'll focus on fixing bugs from 1-2 because these are the most common interfaces for this library.</p>
<p dir="auto">Then I'd move to (3), and possibly to (4) as these bugs do not affect any applications I'm aware of.</p>
