+* A buffer overflow in gethostbyname_r and related functions performing DNS
+  requests has been fixed.  If the NSS functions were called with a
+  misaligned buffer, the buffer length change due to pointer alignment was
+  not taken into account.  This could result in application crashes or,
+  potentially arbitrary code execution, using crafted, but syntactically
+  valid DNS responses.  (CVE-2015-1781)
+
+* A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
+  for LD and GD on x86 and x86-64, has been implemented.  You will need
+  binutils-2.24 or later to enable this optimization.
 
 * Character encoding and ctype tables were updated to Unicode 7.0.0, using
