<p><em>October 23, 2013</em></p>
<p>Django 1.5.5 fixes a couple security-related bugs and several other bugs in the
1.5 series.</p>
<div class="section" id="s-readdressed-denial-of-service-via-password-hashers">
<span id="readdressed-denial-of-service-via-password-hashers"></span><h2>Readdressed denial-of-service via password hashers<a class="headerlink" href="#readdressed-denial-of-service-via-password-hashers" title="Permalink to this headline">¶</a></h2>
<p>Django 1.5.4 imposes a 4096-byte limit on passwords in order to mitigate a
denial-of-service attack through submission of bogus but extremely large
passwords. In Django 1.5.5, we’ve reverted this change and instead improved
the speed of our PBKDF2 algorithm by not rehashing the key on every iteration.</p>

<p>This behavior introduced as a security hardening measure in Django 1.5.2 did
not work properly and is now fixed.</p>
