How to fix?

Upgrade Oracle:7 openssl-libs to version 2:1.0.1e-51.ksplice1.el7_2.7 or higher.
This issue was patched in ELSA-2016-3621.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl-libs package and not the openssl-libs package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The tls_decrypt_ticket function in ssl/t1_lib.c in OpenSSL before 1.1.0 does not consider the HMAC size during validation of the ticket length, which allows remote attackers to cause a denial of service via a ticket that is too short.
