CVE-2016-2178  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade Ubuntu:16.04 openssl to version 1.0.2g-1ubuntu4.4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack.
