CVE-2016-2179 (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 DTLS implementation in OpenSSL before 1.1.0 does not properly restrict the lifetime of queue entries associated with unused out-of-order messages, which allows remote attackers to cause a denial of service (memory consumption) by maintaining many crafted DTLS sessions simultaneously, related to d1_lib.c, statem_dtls.c, statem_lib.c, and statem_srvr.c.
