<p>This document describes the changes made to the software between the
<em>previous</em> and <em>current</em> versions (see above). If you don’t
find something listed here, then it was not done in this timeframe, or
it was not considered important enough to be mentioned. The following
information is located here:</p>

<section id="library-changes">
<h2>Library changes<a class="headerlink" href="#library-changes" title="Permalink to this heading">¶</a></h2>
<ul class="simple">
<li><p>Fixed inadequate validation of the <code class="docutils literal notranslate"><span class="pre">SubjectDistance</span></code> field.</p></li>
<li><p>Fixed bad handling of out of order tags definated late by a codec.</p></li>
<li><p>Avoid re-preparing jpeg tables unnecessarily.</p></li>
</ul>
</section>
<section id="tools-changes">
<h2>Tools changes<a class="headerlink" href="#tools-changes" title="Permalink to this heading">¶</a></h2>
<ul class="simple">
<li><p><strong class="program">tiffcrop</strong>: Added an option to allow the user to specify a
custom page size on the command line. Fix the case where a
page size specified with a fractional part was being coerced
to an integer by retyping the variables that define the paper
size. Corrected European page size dimensions.</p></li>
<li><p><strong class="program">tiff2rgba</strong>: Completed fixes for “<a class="reference external" href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-2347">CVE-2009-2347</a> libtiff:
integer overflows in various inter-color space conversion
tools”. <a class="reference external" href="http://bugzilla.maptools.org/show_bug.cgi?id=2079">MapTools bugzilla #2079</a></p></li>
<li><p><strong class="program">tiff2pdf</strong>: Fix assorted bugs in <strong class="program">tiff2pdf</strong>: missing <code class="docutils literal notranslate"><span class="pre">return</span></code>
in <code class="xref c c-func docutils literal notranslate"><span class="pre">t2p_read_tiff_size()</span></code> causes <code class="docutils literal notranslate"><span class="pre">t2p->tiff_datasize</span></code> to be set entirely
wrong for <code class="xref c c-macro docutils literal notranslate"><span class="pre">COMPRESSION_JPEG</span></code> case, resulting in memory stomp if actual
size is larger. Also, there are a bunch of places that try to
<code class="xref c c-func docutils literal notranslate"><span class="pre">memset()</span></code> a malloc’d buffer before checking for malloc failure, which
would result in core dump if there actually were a failure.</p></li>
