How to fix?

Upgrade RHEL:7 curl to version 0:7.29.0-35.el7 or higher.
This issue was patched in RHSA-2016:2575.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by RHEL. See How to fix? for RHEL: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.
