Modification date: 27 Nov 2018
Type: security
Affected Mageia releases : 6
CVE: CVE-2018-0734 , CVE-2018-5407

Description

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. Fixed in OpenSSL 1.1.1a
(Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed
in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p). (CVE-2018-0734)

Simultaneous Multi-threading (SMT) in processors can enable local users
to exploit software vulnerable to timing attacks via a side-channel
timing attack on 'port contention'. (CVE-2018-5407
