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.
