Debian Bug : 873383

Daniel Genkin, Luke Valenta and Yuval Yarom discovered that Libgcrypt
is prone to a local side-channel attack against the ECDH encryption with
Curve25519, allowing recovery of the private key.

See https://eprint.iacr.org/2017/806 for details.

For the stable distribution (stretch), this problem has been fixed in
version 1.7.6-2+deb9u2.
