Debian: DSA-3650-1 Critical: Libgcrypt20 RNG Attack Overview
debian
August 17, 2016
Felix Doerre and Vladimir Klebanov from the Karlsruhe Institute of Technology discovered a flaw in the mixing functions of Libgcrypt's random number generator
Summary
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.
