Security Fix(es):

  * A design flaw was found in the libgcrypt PRNG (Pseudo-Random Number
Generator). An attacker able to obtain the first 580 bytes of the PRNG
output could predict the following 20 bytes. (CVE-2016-6313)

Red Hat would like to thank Felix Dorre and Vladimir Klebanov for reporting
this issue.");
