CWE-390  (opens in a new tab)

How to fix?

Upgrade RHEL:7 openssl to version 1:1.0.1e-34.el7_0.4 or higher.
This issue was patched in RHSA-2014:1052.

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 ssl23_get_client_hello function in s23_srvr.c in OpenSSL 1.0.1 before 1.0.1i allows man-in-the-middle attackers to force the use of TLS 1.0 by triggering ClientHello message fragmentation in communication between a client and server that both support later TLS versions, related to a "protocol downgrade" issue.
