Note: Versions mentioned in the description apply only to the upstream libgcrypt20 package and not the libgcrypt20 package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
Libgcrypt before 1.8.1 does not properly consider Curve25519 side-channel attacks, which makes it easier for attackers to discover a secret key, related to cipher/ecc.c and mpi/ec.c.
