7.5/10

Summary

The DTLS implementation in OpenSSL before 1.0.1u and 1.0.2 through 1.0.2i, 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".
