CWE-310  (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-1ubuntu4.1 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 AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169.
