PATCH 1/1 libopenssl: security bump to version 1.0.2q

Fixes the following security vulnerabilities:

*) Microarchitecture timing vulnerability in ECC scalar multiplication

OpenSSL ECC scalar multiplication, used in e.g. ECDSA and ECDH, has been shown to be vulnerable to a microarchitecture timing side channel attack. An attacker with sufficient access to mount local timing attacks during ECDSA signature generation could recover the private key.

This issue was reported to OpenSSL on 26th October 2018 by Alejandro Cabrera Aldaya, Billy Brumley, Sohaib ul Hassan, Cesar Pereida Garcia and Nicola Tuveri.
(CVE-2018-5407)
[Billy Brumley]

*) Timing vulnerability in DSA signature generation

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key.

This issue was reported to OpenSSL on 16th October 2018 by Samuel Weiser. (CVE-2018-0734)
[Paul Dale]
