Upgrade Amazon-Linux:2018.03 openssl-devel to version 1:1.0.1k-15.96.amzn1 or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl-devel package and not the openssl-devel package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2018.03 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.
