Synopsis

The remote Debian host is missing a security update.

Description

CVE-2018-0735 Samuel Weiser reported a timing vulnerability in the OpenSSL ECDSA signature generation, which might leak information to recover the private key.

CVE-2018-5407 Alejandro Cabrera Aldaya, Billy Brumley, Sohaib ul Hassan, Cesar Pereida Garcia and Nicola Tuveri reported a vulnerability to a timing side channel attack, which might be used to recover the private key.
