Felix Dörre and Vladimir Klebanov from the Karlsruhe Institute of
Technology found a bug in the mixing functions of Libgcrypt’s random
number generator: An attacker who obtains 4640 bits from the RNG can
trivially predict the next 160 bits of output. This bug exists since
1998 in all GnuPG and Libgcrypt versions.
