+  *) Timing vulnerability in DSA signature generation
+
+     The OpenSSL DSA signature algorithm has been shown to be vulnerable to a
+     timing side channel attack. An attacker could use variations in the signing
+     algorithm to recover the private key.
+
+     This issue was reported to OpenSSL on 16th October 2018 by Samuel Weiser.
