+  <title>FLAC: Buffer overflow</title>
+  <synopsis>
+    Multiple integer overflow vulnerabilities were found in FLAC possibly
+    allowing for the execution of arbitrary code.

+    <p>
+    The Xiph.org Free Lossless Audio Codec (FLAC) library is the reference
+    implementation of the FLAC audio file format. It contains encoders and
+    decoders in library and executable form.

+  <description>
+    <p>
+    Sean de Regge reported multiple integer overflows when processing FLAC
+    media files that could lead to improper memory allocations resulting in
+    heap-based buffer overflows.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user to open a specially crafted FLAC
+    file or network stream with an application using FLAC. 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 FLAC users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/flac-1.2.1-r1&quot;</code>
+    <p>
+    You should also run revdep-rebuild to rebuild any packages that depend
+    on older versions of FLAC:
+    </p>
+    <code>
+    # revdep-rebuild --library=libFLAC.*</code>
