<a id="user-content-description-of-problem" class="anchor" href="#description-of-problem" aria-hidden="true"></a>Description of problem:</h2>
<p dir="auto">p11tool is able to display the PKCS#11 URI for an object with a CKA_ID longer than 42 bytes, but crashes when displaying the colon-delimited version.</p>
<p dir="auto">As far as I know, the PKCS#11 spec puts no limit on the size of a CKA_ID.</p>

<a id="user-content-version-of-gnutls-used" class="anchor" href="#version-of-gnutls-used" aria-hidden="true"></a>Version of gnutls used:</h2>

<a id="user-content-how-reproducible" class="anchor" href="#how-reproducible" aria-hidden="true"></a>How reproducible:</h2>
<p dir="auto">Steps to Reproduce:</p>
<ul dir="auto">
<li>Using some other tool, create an object with an pretty long CKA_ID. I triggered this with a 68 byte ID.</li>
<li>Invoke <code>p11tool --list-all</code> on the token.</li>
</ul>

<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code><span id="LC1" class="line" lang="plaintext">$ p11tool --list-all 'pkcs11:model=SLB9670'Object 0:</span>
<span id="LC2" class="line" lang="plaintext"> URL: pkcs11:model=SLB9670;manufacturer=IFX;serial=;token=TPM2.0;id=%30%30%30%62%30%37%62%63%34%37%66%33%37%33%63%35%36%37%64%38%32%31%61%61%30%63%61%34%63%38%36%36%37%65%66%62%66%39%36%62%32%62%64%34%32%37%34%61%36%39%36%30%30%66%33%65%65%39%37%35%37%32%38%38%31%31%30%34;type=public</span>
<span id="LC3" class="line" lang="plaintext"> Type: Public key</span>
<span id="LC4" class="line" lang="plaintext"> Label: </span>
<span id="LC5" class="line" lang="plaintext">Error in pkcs11_list:333: The given memory buffer is too short to hold parameters.</span></code></pre>
<h2 dir="auto">
<a id="user-content-expected-results" class="anchor" href="#expected-results" aria-hidden="true"></a>Expected results:</h2>
<p dir="auto">Manually truncating the CKA_ID to 42 bytes with my PKCS#11 library, I can get it to print the ID out.</p>
<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code></code></pre>
