+    possibly the execution of arbitrary code when viewing malicious PowerPoint
+    files.

+    <p>
+    Kees Cook of Ubuntu discovered that 'KLaola::readBigBlockDepot()' in
+    klaola.cc fills 'num_of_bbd_blocks' while reading a .ppt (PowerPoint)
+    file without proper sanitizing, resulting in an integer overflow
+    subsequently overwriting the heap with parts of the file being read.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    By enticing a user to open a specially crafted PowerPoint file, an
+    attacker could crash the application and possibly execute arbitrary
+    code with the rights of the user running KOffice.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All koffice-libs users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-office/koffice-libs-1.5.0&quot;</code>
