CVE-2014-0076  (opens in a new tab)
CWE-310  (opens in a new tab)

How to fix?

Upgrade Ubuntu:12.04 openssl to version 1.0.1-4ubuntu5.12 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:12.04 relevant fixed versions and status.

The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack.
