CVE-2016-2181 (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 Anti-Replay feature in the DTLS implementation in OpenSSL before 1.1.0 mishandles early use of a new epoch number in conjunction with a large sequence number, which allows remote attackers to cause a denial of service (false-positive packet drops) via spoofed DTLS records, related to rec_layer_d1.c and ssl3_record.c.
