+	  <p>Fix a potential security vulnerability where an untrusted
+	    filesystem can be corrupted in such a way that a program using
+	    libext2fs will allocate a buffer which is far too small.  This can
+	    lead to either a crash or potentially a heap-based buffer overflow
+	    crash.  No known exploits exist, but main concern is where an
+	    untrusted user who possesses privileged access in a guest Xen
+	    environment could corrupt a filesystem which is then accessed by
+	    the pygrub program, running as root in the dom0 host environment,
+	    thus allowing the untrusted user to gain privileged access in the
+	    host OS.  Thanks to the McAfee AVERT Research group for reporting
+	    this issue.</p>
