<blockquote>
<h2>v0.6.4</h2>
<!-- raw HTML omitted -->
<h2>What's Changed</h2>
<h3>🔒 Security</h3>
<p>This release contains fixes for <strong>multiple vulnerabilities</strong> concerning <em><strong><code>STARTTLS</code> stripping</strong></em>, argument validation, and denial of service attacks.</p>
<blockquote>
<p>[!WARNING]
<a href="https://redirect.github.com/ruby/net-imap/pull/664">ruby/net-imap#664</a> fixes a <code>STARTTLS</code> stripping vulnerability (GHSA-vcgp-9326-pqcp).
Without this fix, a man-in-the-middle attacker can cause <code>Net::IMAP#starttls</code> to return "successfully", <strong><em>without starting TLS</em></strong>.</p>
</blockquote>
<blockquote>
<p>[!IMPORTANT]
Argument validation is significantly improved. Several injection vulnerabilities have been fixed:
<a href="https://redirect.github.com/ruby/net-imap/pull/657">ruby/net-imap#657</a> fixes CRLF/command/argument injection via Symbol arguments (GHSA-75xq-5h9v-w6px).
<a href="https://redirect.github.com/ruby/net-imap/pull/658">ruby/net-imap#658</a> fixes CRLF/command/argument injection via the <code>attr</code> argument to <code>#store</code>/<code>#uid_store</code> (GHSA-hm49-wcqc-g2xg)
<a href="https://redirect.github.com/ruby/net-imap/pull/659">ruby/net-imap#659</a> fixes CRLF/command/argument injection via the <code>storage_limit</code> argument to <code>#setquota</code> (GHSA-hm49-wcqc-g2xg).
<a href="https://redirect.github.com/ruby/net-imap/pull/660">ruby/net-imap#660</a> fixes CRLF/command injection via <code>RawData</code> (GHSA-hm49-wcqc-g2xg):</p>
<ul>
<li><code>#search</code> and <code>#uid_search</code> send <code>criteria</code> as raw data, when it is a String</li>
<li><code>#fetch</code> and <code>#uid_fetch</code> send <code>attr</code> as raw data, when it is a String.
When <code>attr</code> is an Array, its String members are sent as raw data.</li>
</ul>
</blockquote>
<blockquote>
<p>[!CAUTION]
<code>RawData</code> does not defend against <em>other</em> forms of argument injection! It is an intentionally low-level API.</p>
</blockquote>
<blockquote>
<p>[!NOTE]
Two denial of service vulnerabilities have been addressed.
These are generally only relevant when connecting to an <em>untrusted hostile server</em> (or without TLS).</p>
<p><a href="https://redirect.github.com/ruby/net-imap/pull/642">ruby/net-imap#642</a> fixes quadratic time complexity when reading large responses containing many string literals (GHSA-q2mw-fvj9-vvcw).
<a href="https://redirect.github.com/ruby/net-imap/pull/654">ruby/net-imap#654</a> adds a configurable <code>max_iterations</code> count for <code>SCRAM-*</code> authentication (GHSA-87pf-fpwv-p7m7).</p>
<p>The default <code>ScramAuthenticator#max_iterations</code> is <code>2**31 - 1</code> (max 32-bit signed int), which was already OpenSSL's maximum value. <em>It provides no protection</em> against hostile servers unless it is explicitly set to a lower value by the user.</p>
</blockquote>
<h3>Breaking Changes</h3>
<ul>
<li>⚡ <code>ResponseReader</code> memoizes <code>Config#max_response_size</code> in <a href="https://redirect.github.com/ruby/net-imap/pull/642">ruby/net-imap#642</a>.
Changes to <code>#max_response_size</code> now take effect once per response, not on every <code>IO#read</code>.
<em>NOTE: It is not expected that this will affect any current usage.</em> See <a href="https://redirect.github.com/ruby/net-imap/pull/642">the PR</a> for details.</li>
