<impact type="normal">
<p>
By creating a specially crafted data stream, attackers can
overwrite data structures for applications that use Pngcrush, resulting
in a Denial of Service and potentially arbitrary code execution.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Pngcrush users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/pngcrush-1.6.2&quot;</code>
</resolution>
