+  <description>
+    <p>
+    Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
+    buffer overflow in zlib. A bounds checking operation failed to take
+    invalid data into account, allowing a specifically malformed deflate
+    data stream to overrun a buffer.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    An attacker could construct a malformed data stream, embedding it
+    within network communication or an application file format, potentially
+    resulting in the execution of arbitrary code when decoded by the
+    application using the zlib library.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All zlib users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=sys-libs/zlib-1.2.2-r1&quot;</code>
