CVE-2016-2179 (opens in a new tab)How to fix?
Upgrade RHEL:7 openssl to version 1:1.0.1e-51.el7_2.7 or higher.
This issue was patched in RHSA-2016:1940.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by RHEL.
See How to fix? for RHEL:7 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.
