Detail
| 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. For the unstable distribution (sid), this problem has been fixed in version 1.7.9-1. We recommend that you upgrade your libgcrypt20 packages. |
