<background>
<p>
libsndfile is a C library for reading and writing files containing
sampled sound.
</p>
</background>
<description>
<p>
The following vulnerabilities have been found in libsndfile:
</p>
<ul>
<li>Tobias Klein reported that the header_read() function in
src/common.c uses user input for calculating a buffer size, possibly
leading to a heap-based buffer overflow (CVE-2009-1788).</li>
<li>The
vendor reported a boundary error in the aiff_read_header() function in
src/aiff.c, possibly leading to a heap-based buffer overflow
(CVE-2009-1791).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted AIFF
or VOC file in a program using libsndfile, possibly resulting in the
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-1.0.20&quot;</code>
</resolution>
