+2015
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* 2015-08-03 (CVE-2015-5726)
+
+  The BER decoder would crash due to reading from offset 0 of an empty vector if
+  it encountered a BIT STRING which did not contain any data at all. This can be
+  used to easily crash applicatons reading untrusted ASN.1 data, but does not
+  seem exploitable for code execution. Found with afl.
+
+  Fixed in 1.11.19 and 1.10.10, affected all previous versions of 1.10 and 1.11
+
+* 2015-08-03 (CVE-2015-5727)
+
+  The BER decoder would allocate a fairly arbitrary amount of memory in a length
+  field, even if there was no chance the read request would succeed.  This might
+  cause the process to run out of memory or invoke the OOM killer. Found with afl.
+
+  Fixed in 1.11.19 and 1.10.10, affected all previous versions of 1.10 and 1.11
+
+2014
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* 2014-04-10 (CVE-2014-9742)
+
+  A bug in the Miller-Rabin primality test resulted in only a single random base
+  being used instead of a sequence of such bases. This increased the probability
+  that a non-prime would be accepted by is_prime or that a randomly generated
+  prime might actually be composite.  The probability of a random 1024 bit
+  number being incorrectly classed as prime with a single base is around 2^-40.
+  Reported by Jeff Marrison.
+
+  Fixed in 1.11.9 and 1.10.8, affected all versions since 1.8.3
