How to fix?

Upgrade Oracle:7 libcurl to version 0:7.29.0-35.el7 or higher.
This issue was patched in ELSA-2016-2575.

NVD Description

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

curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.
