<p>
Alin Rad Pop from Secunia Research reported an integer overflow when
processing CAF description chunks, leading to a heap-based buffer
overflow.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted CAF
file, resulting in the remote execution of arbitrary code with the
privileges of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libsndfile users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libsndfile-1.0.19&quot;</code>
</resolution>
