+    <p>Boost is a set of C++ libraries, including the Boost.Regex library to
+      process regular expressions.

+  <description>
+    <p>It was discovered that Boost incorrectly sanitized ‘next_size’ and
+      ‘max_size’ parameter in ordered_malloc() function when allocating
+      memory.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>A remote attacker could provide a specially crafted application-specific
+      file (requiring runtime memory allocation to be processed correctly),
+      that, when opened with an application using Boost C++ source libraries,
+      possibly resulting in execution of arbitrary code with the privileges of
+      the process or a Denial of Service condition.

+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All Boost users should upgrade to the latest version:</p>
