+Subject: [PATCH] Avoid some undefined pointer arithmetic
+
+A common idiom in the codebase is:
+
+if (p + len > limit)
+{
+ return; /* Too long */
+}
+
+Where "p" points to some malloc'd data of SIZE bytes and
+limit == p + SIZE
+
+"len" here could be from some externally supplied data (e.g. from a TLS
+message).
+
+The rules of C pointer arithmetic are such that "p + len" is only well
+defined where len <= SIZE. Therefore the above idiom is actually
+undefined behaviour.
+
+For example this could cause problems if some malloc implementation
+provides an address for "p" such that "p + len" actually overflows for
+values of len that are too big and therefore p + len < limit!
+
+Issue reported by Guido Vranken.

+Subject: [PATCH 1/2] Fix DSA, preserve BN_FLG_CONSTTIME
+
+Operations in the DSA signing algorithm should run in constant time in
+order to avoid side channel attacks. A flaw in the OpenSSL DSA
+implementation means that a non-constant time codepath is followed for
+certain operations. This has been demonstrated through a cache-timing
+attack to be sufficient for an attacker to recover the private DSA key.
