An attacker who obtains 4640 bits from the RNG can trivially predict the next 160 bits of output. A first analysis on the impact of this bug for GnuPG shows that existing RSA keys are not weakened. For DSA and Elgamal keys it is also unlikely that the private key can be predicted from other public information. For the stable distribution (jessie), this problem has been fixed in version 1.6.3-2+deb8u2. We recommend that you upgrade your libgcrypt20 packages.
