CVE-2015-7744 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:16.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream mariadb-10.0 package and not the mariadb-10.0 package as distributed by Ubuntu.
wolfSSL (formerly CyaSSL) before 3.6.8 does not properly handle faults associated with the Chinese Remainder Theorem (CRT) process when allowing ephemeral key exchange without low memory optimizations on a server, which makes it easier for remote attackers to obtain private RSA keys by capturing TLS handshakes, aka a Lenstra attack.
