<background>
<p>Gnash is a GNU flash movie player that supports many SWF features.</p>
</background>
<description>
<p>Multiple vulnerabilities have been found in Gnash:</p>
<ul>
<li>The "nsPluginInstance::setupCookies()" function in plugin.cpp creates
world-readable cookies with predictable file names (CVE-2011-4328).
</li>
<li>The "GnashImage::size()" function in GnashImage.h contains an integer
overflow error which could cause a heap-based buffer overflow
(CVE-2012-1175).
</li>
</ul>
</description>
<impact type="normal">
<p>A remote attacker could entice a user to open a specially crafted SWF
file, possibly resulting in execution of arbitrary code or a Denial of
Service condition. Furthermore, a local attacker may be able to obtain
sensitive information.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All Gnash users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=www-plugins/gnash-0.8.10-r2"
</code>
</resolution>
