+  <title>libsndfile: Buffer overflow</title>
+  <synopsis>
+    A buffer overflow vulnerability has been discovered in libsndfile.
+  </synopsis>

+  <affected>
+    <package name="media-libs/libsndfile" auto="yes" arch="*">
+      <unaffected range="ge">1.0.17-r1</unaffected>

+  <background>
+    <p>
+    libsndfile is a library for reading and writing various formats of
+    audio files including WAV and FLAC.
+    </p>
+  </background>
+  <description>
+    <p>
+    Robert Buchholz of the Gentoo Security team discovered that the
+    flac_buffer_copy() function does not correctly handle FLAC streams with
+    variable block sizes which leads to a heap-based buffer overflow
+    (CVE-2007-4974).
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could exploit this vulnerability by enticing a user
+    to open a specially crafted FLAC file or network stream with an
+    application using libsndfile. This might lead to the execution of
+    arbitrary code with privileges of the user playing the file.
+    </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-1.0.17-r1&quot;</code>
