Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that Libgcrypt is prone to a local side-channel attack allowing recovery of ECDSA private keys.

For Debian 8 'Jessie', these problems have been fixed in version 1.6.3-2+deb8u5.

We recommend that you upgrade your libgcrypt20 packages.
