+  <description>
+    <p>
+    Carsten Lohrke of Gentoo Linux reported that Pngcrush contains a
+    vulnerable version of zlib (GLSA 200507-19).
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    By creating a specially crafted data stream, attackers can
+    overwrite data structures for applications that use Pngcrush, resulting
+    in a Denial of Service and potentially arbitrary code execution.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Pngcrush users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/pngcrush-1.6.2&quot;</code>
