+  <title>libsndfile: User-assisted execution of arbitrary code</title>
+  <synopsis>
+    Multiple heap-based buffer overflow vulnerabilities in libsndfile might
+    allow remote attackers to execute arbitrary code.

+  <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>
