Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache
side-channel attack on ECDSA signatures that can be mitigated through the
use of blinding during the signing process in the _gcry_ecc_ecdsa_sign
function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem
or ROHNP. To discover an ECDSA key, the attacker needs access to either the
local machine or a different virtual machine on the same physical host.
