+  <background>
+    <p>bsdiff and bspatch are tools for building and applying patches to binary
+      files.
+    </p>
+  </background>
+  <description>
+    <p>It was discovered that the implementation of bspatch did not check for a
+      negative value on numbers of bytes read from the diff and extra streams.
+    </p>
+  </description>
+  <impact type="high">
+    <p>A remote attacker could entice a user to apply a specially crafted patch
+      using bspatch, possibly resulting in execution of arbitrary code with the
+      privileges of the process or a Denial of Service condition.
+    </p>
+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All Binary diff users should upgrade to the latest version:</p>
+    
+    <code>
+      # emerge --sync
+      # emerge --ask --oneshot --verbose "&gt;=dev-util/bsdiff-4.3-r4"
